How to Troubleshoot Errors that Occur When Connectivity Test Cmdlets Are Run on a 32-Bit Version of Windows XP

 

Topic Last Modified: 2009-01-26

This topic describes how to troubleshoot error messages that occur when you run cmdlets to test connectivity to Microsoft Exchange Server 2007 on a computer that is running a 32-bit version of Windows XP.

Test cmdlets test specific Exchange 2007 components and provide log files that you can examine. When you try to run test cmdlets on a 32-bit version of Windows XP, you receive one of the following error messages:

 

[PS] C:\>Test-OwaConnectivity -ClientAccessServer CASServer.Domain.com -MailboxServer MBXServer.Domain.com

WARNING: Test user 'User_Name' cannot be accessed. Therefore, this cmdlet will be unable to test Mailbox server 'MBXServer.Domain.com'.

Test-OwaConnectivity : Could not find or log on with user Domain.com\User_Name. If this task is being run without credentials, log on as a Domain Administrator, and then run the new-TestCasConnectivityUser.ps1 to verify that the user exists on Mailbox server MBXServer.Domain.com

At line:1 char:21

+ Test-OwaConnectivity <<<< -ClientAccessServer CASServer.Domain.com -MailboxServer MBXServer.Domain.com

WARNING: No Client Access servers were tested.

 

[PS] C:\>Test-ActiveSyncConnectivity -ClientAccessServer CASServer.Domain.com -MailboxServer MBXServer.Domain.com

WARNING: Test user 'CAS_5323d9a976d24a77' cannot be accessed. Therefore, this cmdlet will be unable to test Mailbox server 'MBXServer.Domain.com'.

Test-ActiveSyncConnectivity : Could not find or log on with user Domain.com\CAS_5323d9a976d24a77. If this task is being run without credentials, log on as a Domain Administrator, and then run the new-TestCasConnectivityUser.ps1 to verify that the user exists on Mailbox server MBXServer.Domain.com

At line:1 char:28

+ Test-ActiveSyncConnectivity <<<< -ClientAccessServer CASServer.Domain.com -MailboxServer MBXServer.Domain.com

WARNING: No Client Access servers were tested.

This error occurs because the 32-bit version of Windows XP does not use the KERB_S4U_LOGON structure. The KERB_S4U_LOGON structure is called by the LSALogonUser function when a user credential is not passed to the server. This error does not occur on computers that are running the 64-bit version of Windows XP.

For more information about the KERB_S4U_LOGON structure, see KERB_S4U_LOGON Structure.
