You cannot log on to a local intranet site that you publish by using ISA Server 2006 when there are multiple user accounts that have the same account name in different domains

Symptoms
Consider the following scenario:
  • You use Microsoft Internet Security and Acceleration (ISA) Server 2006 to publish a local intranet site.
  • You enable forms-based authentication (FBA) and the Allow users to change their passwords feature for the Web Listener.
  • The ISA Server is a member of a domain. For example, the domain is Domain1.
  • There are multiple domains in the forest, and there are user accounts that exist with the same account name in different domains. For example, the user accounts are Domain1\user1 and Domain2\user1.
  • One of the user accounts is disabled. For example, Domain1\user1 is disabled.
  • You try to use the other user account to log on to the local intranet site. For example, you use Domain2\user1 to log on to the local intranet site.
In this scenario, you receive the following error message:
Your account has been disabled. Please contact technical support for your organization.
Additionally, you cannot log on to the local intranet site.
Cause
This problem occurs because ISA Server first searches for the user name in the domain where the ISA Server exists. Then, ISA Server finds an account that has the same account name. However, this is not the correct user account that the user requested.
Resolution
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure. However, they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

To resolve this problem, follow these steps:
  1. Install ISA Server 2006 Service Pack 1. For more information about how to obtain ISA Server 2006 Service Pack 1, click the following article number to view the article in the Microsoft Knowledge Base:
    954258 How to obtain the latest Internet Security and Acceleration (ISA) Server 2006 service pack
  2. Run a script to enable the functionality that is provided by this service pack. To do this, follow these steps:
    1. Click Start, click Run, type notepad, and then click OK.
    2. Copy the following script into a Notepad file, and then save the text file as a Microsoft Visual Basic file by using the .vbs file name extension.
      Const SE_VPS_GUID = "{143F5698-103B-12D4-FF34-1F34767DEabc}"Const SE_VPS_NAME = "EnableMultipleFlatUserName"Const SE_VPS_VALUE = trueSub SetValue()    ' Create the root obect.    Dim root  ' The FPCLib.FPC root object    Set root = CreateObject("FPC.Root")    'Declare the other objects needed.    Dim array       ' An FPCArray object    Dim VendorSets  ' An FPCVendorParametersSets collection    Dim VendorSet   ' An FPCVendorParametersSet object    ' Get references to the array object    ' and the network rules collection.    Set array = root.GetContainingArray    Set VendorSets = array.VendorParametersSets    On Error Resume Next    Set VendorSet = VendorSets.Item( SE_VPS_GUID )    If Err.Number <> 0 Then        Err.Clear        ' Add the item        Set VendorSet = VendorSets.Add( SE_VPS_GUID )        CheckError        WScript.Echo "New VendorSet added... " & VendorSet.Name    Else        WScript.Echo "Existing VendorSet found... value- " &  VendorSet.Value(SE_VPS_NAME)    End If    if VendorSet.Value(SE_VPS_NAME) <> SE_VPS_VALUE Then        Err.Clear        VendorSet.Value(SE_VPS_NAME) = SE_VPS_VALUE        If Err.Number <> 0 Then            CheckError        Else            VendorSets.Save false, true            CheckError            If Err.Number = 0 Then                WScript.Echo "Done with " & SE_VPS_NAME & ", saved!"            End If        End If    Else        WScript.Echo "Done with " & SE_VPS_NAME & ", no change!"    End IfEnd SubSub CheckError()    If Err.Number <> 0 Then        WScript.Echo "An error occurred: 0x" & Hex(Err.Number) & " " & Err.Description        Err.Clear    End IfEnd SubSetValue
    3. Save the file to a temporary folder. For example, save the file as EnableMultipleFlatUserName.vbs to the C:\EnableMultipleFlatUserName folder.
    4. At a command prompt, move to the location in which you saved the .vbs file in step 2c, and then run the .vbs file. For example, run the following commands:
      cd C:\EnableMultipleFlatUserName
      cscript EnableMultipleFlatUserName.vbs
