wrong version of project dll’s invoked

c:\inetpub\AAv6 (production – baseline & QW1)
c:\inetpub\AAv7 (UAT – QW2)
c:\inetpub\AAv8 (Dev – QW3)

Debugging v7 on my box was actually picking up the v8 version of SOME of the files (not sure if the v8 versions were put into the released binaries or the v7, primary (UI) binaries were v7 else I would have noticed a lot sooner). Primary offender was AAClasses.

This led to all sorts of “No, that can’t happen”, “Shit”, “That’s impossible”, “wtf”, “omg” & “huh?” behaviours.


1.) Close IDE
2.) Reboot (even w/ IDE closed (and killing all iis-related processes) there are still file locks on some of the dll’s & it was taking forever to identify these processes)
3.) DO NOT start IDE
4.) (didn’t help, but for giggles) kill the pdb files in the solution’s bin folders
5.) rd /s /q all dirs under C :\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\root
rd /s /q "C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\root\"
a.) this will removed the cached binaries
b.) will make the first run of your project take forever so run through the whole thing once before you try to do any tracing/debugging
6.) Rename the root directory to make sure the ap does not find those binaries (Note – searching project and solution manifests revealed no references to the incorrect files)
7.) Test – you should now be playing with what you intended.

Some Instances of IE Not Allowing Access to Secure Site


But what it does not say is … if you have a complex site w/ differing directory permissions on different levels you must specify the “NTAuthenticationProviders” property on root as well as the subdirectories. (Note- this is not available via the IIS UI)

Anonymous access (“Allow” checkbox) will override this so it can be set on all subdirs.

In English, the following should be included in the node definition


Else some IE browser will try to use Kerberos authentication (vs. integrated) & you will get a “Cannot access page” error w/ no detail whatsoever.

A quick test of whether or not Kerberos is mucking w/ you can be done using WFetch (screenshot sample below). You want to look for “Authentication:Negotiate” in the response stream. If it is there then IIS is trying to use Kerberos authentication and the above fix will force integrated/NTAuth.

Solution to "An error occurred in the secure channel support" - VS 2003 & https redirection

A.) (Blow away/move) the application’s dll (i.e. [bin]\[foo.dll]). Note – if you just do a rename you will get and assembly binding error.


Case (global.asax):

protected void Application_BeginRequest(Object sender, EventArgs e)
Response.Redirect(Request.Url.ToString().Replace("http://", "https://"));

On a dev box that does not support ssl (& if you are using ports that is another issue).

Compiles fine.

Close & reopen devenv & project …

Upon load, the devenv parses the ap_load dll to contact the web server (2003 uses IIS, 2005 uses Casini and may not demonstrate the same issues) however now the ap_load is redirecting the URI (protocol) the ap uses to go the web server, cannot find the site and barfs.

You are now left with a “You can’t get there from here” ( situation.

By removing the compiled version of the project, the site (existence) is not validated at dev time but rather run time (which then at least allows you to still modify the code, say do a conditional redirection based on environment).

    Visual Studio 2003 Deployment

    Project / Copy Project

    Do not use FPS rather use the UI to XCOPY to a local (pre-made) site, only files needed for this project.


    I discovered this three ways (perhaps because I can be particularly obtuse @ times ...)

    1.) Code I rolled did not do what it should ... (Gee, duh ... (and yes, I was staging it))

    2.) Funny thing how the VS deployment tool would finish so quickly after encountering an error (i.e. it took 30 seconds when an XCOPY took 2 minutes or more ...)

    3.) Hmmm ... My local solution has a rather complex file hierarchy but ... I only see first level hierarchy (and for the immediate sub-levels there are no contents) ... Not sure about the priority/pattern of XCOPY (about which I am guessing the VS 2003 IDE is trying to obfuscate) but ... isn't it funny that if "img21.jpg" & "img22.jpg" (of a second level directory) are there but it bombs (modal) on "img23.jpg" (which it turns out is missing in source but is in VSS manifest) and then "img24.jpg" is not in the subdirectory of the deployed/stage solution (after one hits "OK" on the modal) (but it is in the source directory ...)

    Point: Not sure about the exact order of a VS "Copy Project" deployment but if there is an error it is fatal, does not rollback and can leave you with a partial/mixed deployment if you don't stage (use good practices).

    2003 to 2005 Conversion: "Unable to start debugging on the web server"

    Make sure your project did not inherit a port that is configured for 1.1 (i.e. start project properties, web tab, "Use Visual Studio Development Server")

    Visual Studio - Just Cannot Get Those Reference Paths Right ...


    C:\Inetpub\dir1.1\resources\foo.dll (i.e. 1.1 version)
    C:\Inetpub\dir2.0\resources\foo.dll (i.e. 2.0 version)

    You want to add the latter (the 2.0 version in dir2.0) to your project references but, after you do so and you go back and check the properties of foo.dll in your project you see that it is pointing to the former (the 1.1 version in dir1).

    Check "Project Properties", the "Reference Paths" tab values and remove the paths to any unused directories. These act similarly to path variables and if foo.dll is found in one of them then that is the file that will be used regardless of the fully qualified path that you explicitly specified.

    More on Secure Channel Support

    Visual Studio 2003 (.Net 1.1)

    "Secure Channel Support" errors have occurred quite frequently. Common resolutions have been:

    + (Deployment) use XCOPY, not FPS
    + (IDE) change port, make sure to change definitions in solution file and file (I think this file is specific to 1.1/2003)

    Resolution for this instance of the debacle ... one of the eight project files (in the solution) I had converted to 2005 (the only indication being the rather obtuse error). "Secure Channel Support" errors were evident prior to any 2005 conversion efforts and (from what I gather online) have been the bane of many. Discovery of the difference was made with line-by-line analysis of each project manifest file and noting that one of the property value of one of the elements referred to "CodeBehind" versus "Inline", a feature (that if I recall correctly) was fully implemented in 2005 (with the introduction of partial classes).

    How to use VS 2003 on Vista

    1.) Visual Studio 2003 is not supported on Vista (per M$). While VS2k3 binaries will run on Vista and VS2k3 code can/will compile on Vista, Vista in not a suitable OS for a VS2k3 development machine. Use 2k Pro+ or XP Pro+
    2.) This document is specific to web projects
    3.) Version of Vista was/is 64 bit Ultimate (only relevant to a few steps)


    1.) .Net Framework 1.1
    2.) .Net Framework 1.1 (Very important – otherwise you will get a rather obtuse error)
    1.) Ensure "c:\Windows\Microsoft.NET\Framework\v1.1.4322\mscorsvr.dll" is version 1.1.4322.2032 or higher
    2.) IIS 6.0 or later (7.0 comes w/ Vista versions Premium and above)

    Detailed: (Source: URL_1)

    1.) Enable IIS 6.0 compatibility
    · Open "Control Panel"
    · Double-click "Programs and Features"
    · Expand "Internet Information Services"
    · Expand "Web Management Tools"
    · Check "IIS 6 Management Compatibility"

    2.) Register v1.1 with IIS
    · Open a CMD prompt
    · Change your directory to c:\Windows\\Framework\v1.1.4322
    · Run "aspnet_regiis -ir -enable"
    · "ir" registers v1.1 with IIS but doesn't change any existing script mappings
    · "enable" marks aspnet_isapi.dll as "Allowed" under "ISAPI and CGI Restrictions"
    · aspnet_regiis should also create a new AppPool under "Application Pools" called "ASP.NET 1.1" that is configured with the "Classic" pipline, and "Enable32BitAppOnWin64" set to true if a 64-bit OS.

    3.) Make the new "ASP.NET 1.1" appPool the default.
    · Open the IIS manager
    · Select the "Web Sites" folder.
    · Under "Actions" on the upper right, click "Set Web Site Defaults..."
    · Change the "Application Pool" setting to "ASP.NET 1.1"

    4.) Setup your user account as a local admin (you want to be in the Debugger User group but this will take care of that) URL_2

    5.) Switch off the "user account control" (optional) [msconfig] [tools] [Disable UAC] URL_3

    6.) IIS – make sure “Front Page Extentions” installed (under WWW Services) (via Add / Remove Windows components)

    7.) IIS – make sure “IIS 6.0 Compatibility” installed (under WWW Services) (via Add / Remove Windows components)

    8.) Make sure WWW Services service is running (and IIS, while you’re at it…)

    9.) IIS – server level – “ISAPI & CGI restrictions” – ensure ASP v1.1 enabled (may be able to set at application level and skip step 13 but I did not try)

    10.) New virtual directory
    a. ASP properties – allow client and server side debugging (even though you won’t be able to debug anyway)
    b. Authentication – Windows

    11.) Verify web site started

    12.) Make project, verify web.config value for debug = true (even though you won’t be able to debug anyway)

    13.) Reset any 2.0 sites to use “Default Application Pool” (2.0) in IIS

    14.) If you get an error like “URL is in the internet zone” change your project properties to local host

    a. From “http://netbios and domain/WebApplication1
    b. To “http://localhost/Web Appliation1/

    Other/Related items

    #1.) New boxes from IT may be missing some web hosting components (hear head banging on desk now)
    (Note I am on Vista 64 bit, IIS 7.0)
    a.) Under add/update/remove Windows components, under IIS, under wwws (world wide web services) there are several options – check them all. I think in other OS’s that wwws is on the same level, not under, iis. I’ve isolated it to this level (but not the exact subcomponent). My solution also worked for Mike who is on XP. Symptom is that IIS cannot serve up any kind of asp(x) page, only htm(l) will work

    #2.) (SQL Server) While the 32 bit client tools for 2K (except for EM) work well with 2K5 (and are much lighter weight) the 32 bit 2K tools (query analyzer) does not work with 2K5 64 bit

    "...One of less known features of Visual Studio 2005 is Script Explorer, hidden in Debug menu where appears only when the debugger is running. This great tool allows easily debug JavaScripts..."

    SQL Server 2005 Long Varchar Storage

    2k vs. 2k5 difference – 2k5 will allow table content to exceed 8060 chars – it puts in a 24 bit ref. & stores the offending data in a different page. Not a great idea but it does prevent the app from breaking.

    SQL Server 2005 Security Option

    Had an ap all of a sudden just stop working today …

    Logon Error: 18487, Severity: 14, State: 1. Logon Login failed for user 'loginname'. Reason: The password of the account has expired. [CLIENT: ]

    Then the password for the login used in your web application has expired. SQL Server 2005 introduced 'Enforce password policy' and/or the 'Enforce password expiration' configurations which use the local policies for password length, complexity and expiration. Depending on how Active Directory, the local policies and your rights are setup, these parameters can be reviewed and changed to dictate how SQL Server uses configurations.

    Differences in SQL Profiler 2000 & 2005

    Between Sysobject changes and changes in the UI for SQL Profiler you may run into some unexpected results when trying to trace DB commands (especially if you are trying to trace on only a specific db (recommended – profiler is a rather heavy tool)).

    You may find the below chart of assistance. Note – in the 2005 version of profiler there is a checkbox on the “Filter” dialogue called “Exclude rows that do not contain values” (this does not exist for the 2000 version). Your filters will not be applied unless this box is checked. Additionally this option is not available when using 2005 tools on a 2000 DB.

    Add user account (or yourself) to the local machine - Computer Management - Local Users and Groups - Groups

    C:\>runas /profile /user:whoopie\my.serviceAccount "c:\winnt\notepad.exe"


    a.) Better to use full path to actual executable

    b.) In Local Security Settings \ User Rights Management, a 'deny' property overrides an 'allow' property. So, if whoopie\my.serviceAccount is in 'Administrators' & 'Administrators' have "Allow to log on ..." but whoopie\my.serviceAccount is also in group 'Foobar' and 'Foobar' has "Deny log on ..." then whoopie\my.serviceAccount will not be able to log on even though the 'Administrators' group is higher than the 'Foobar' group.

    AD Abbreviations Active Directory Attribute WinNT property LDAP property

    Names for Objects in Active Directory
    One of the biggest confusions with Active Directory is the many “names” that can be used to refer to or describe an object. Most of these “names” are attributes (or properties) of the object. There is even a property method called “Name”. A Property Method is actually a method (a function) that calculates a value from other properties.

    Note that the terms “attribute” and “property” are interchangeable. The name of a property or attribute is like the name of a variable. The actual value of the property can be assigned by the network administrator, or sometimes by the system.

    Some of the confusion arises because the same attribute can have a different name depending on the provider used. Even worse is that sometimes the same attribute name can refer to a different attribute, depending on the provider. The following table attempts to clarify the situation.

    The “Name” property of the WinNT provider is sometimes called the “NT Name”, because it is the name used in NT networks. The WinNT “Name” property of a user object is the pre-Windows 2000 logon name. The LDAP provider calls this attribute “sAMAccountName”. The value can be the same as the value assigned to the LDAP “cn” attribute, but it does not have to be. This can be a major source of confusion. You cannot retrieve the “cn” attribute with the WinNT provider.

    The “Name” property method of the LDAP provider is the same as the “cn” property, but with the string “cn=” appended in front. For example, if cn = “TestUser”, then Name = “cn=TestUser”. The "Name" property method returns the Relative Distinguished Name (RDN) of the object.

    The same attribute called “FullName” using the WinNT provider is called “displayName” using LDAP. Many of the other attributes used to identify users are only exposed by the LDAP provider.

    Both providers expose an “AdsPath” attribute, but this is actually a “Property Method”. It is the binding string used to bind to the object with the provider. The LDAP provider also exposes a “distinguishedName” attribute. It is the same as “AdsPath”, but without the provider moniker (“LDAP://”) in the string. The “distinguishedName” property of an object might be something like “cn=TestUser,ou=Sales,dc=MyDomain,dc=com”. It uniquely specifies the object in Active Directory. It includes the Relative Distinguished Name of the object, plus the full path to the container holding the object in Active Directory.

    The “userPrincipalName” is an alternative name for the user to logon with. It is in the form “LogonName@DNSDomain”. For example, it could be “Joe”. This attribute is not always assigned a value in Active Directory.

    The only attributes in the table above that are mandatory are “SAM-Account-Name” and “Common-Name”. If a user object is created with the LDAP provider, values must be specified for both “cn” and “sAMAccountName”. If a user object is created with the WinNT provider, only the “Name” attribute is specified (“SAM-Account-Name”), but “Common Name” is automatically assigned to the same value. If a user object is created in the “Active Directory Users and Computers” MMC, the names default as follows. You specify the “First Name”, “Initials”, and “Last Name” of the user (the “givenName”, “initials”, and “sn” attributes). The field labeled “Full Name” defaults to be . . This string is assigned to the “cn” attribute (Common Name). You are allowed to overwrite the default. The fact that the cn attribute is referred to as “Full Name” is another source of confusion. In the “New Object – user” dialog you are also required to specify a “User logon name”. This, in combination with the DNS domain name, becomes the “userPrincipalName”. Finally, As you key in “User logon name”, the field “pre-Windows 2000 logon name” is filled in for you with the first 20 characters of “User logon name”. This becomes the “sAMAccountName” attribute.

    The full NT name of an Active Directory object is in the form “NetBIOSDomain\sAMAccountName”. An example could be:


    The full LDAP name of the same object could be specified by:


    As you can see, the “sAMAccountName” attribute does not have to be the same as the “cn” attribute. In addition, the DNS domain name ( above) does not have to match the NetBIOS domain name (MyDomain above). This can make “finding” objects in Active Directory difficult. Fortunately, the NameTranslate object is generally available to convert names between these two forms.

    It should be noted that the sAMAccountName attribute of any object must be unique in the domain. The userPrincipalName must be unique in the forest. However, the cn attribute (common name) must only be unique in the container or organizational unit. There can be several objects with the same cn, as long as they are in different containers. Note, however, that the distinguishedName will always be unique in the forest.

    A final concept to discuss is the relative distinguished name, abbreviated RDN. For a user object, this is the common name (cn) attribute. The Name property method returns the RDN. The RDN of any object is the first part of the distinguishedName, abbreviated DN, of the object. For example, if the DN of a computer object is:


    Then, the RDN is “cn=Minnesota”.

    A few naming abbreviations:

    cn Common Name
    ou Organizational Unit
    dc Domain Component
    dn Distinguished Name
    rdn Relative Distinguished Name
    upn User Principal Name
