We have windows authentication problem on some VM desktops with XP Professional sp3. A set of desktop is not able to execute linked server queries while other set do.

Have gone through all of the suggested steps that is in http://blogs.msdn.com/b/sql_protocols/archive/2006/08/10/694657.aspx and that uncovered the fact that instead of KERBEROS that those problem desktops are using TCP, NTLM*.

select net_transport, auth_scheme from sys.dm_exec_connections where session_id=@@spid

------------------------------------------

A - is the middle SQL server 2008 R2 Ent Edition that has a linked server object

B - Linked Server instance(SQL Server 2000 Enterprise Edition)

C - Client Machine(Windows XP desktop)

{net transport, auth_scheme}

C to A

A to B

1

TCP, NTLM*

TCP KERBEROS
Domain Info

--------------------------------------------
1. All A, B, C are running under the same domain
2. SQL Server service domain account is common on both A and B
Error reported while trying to execute linked server query:

------------------------------------------------

Msg 18452, Level 14, State 1, Line 0
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

After I enabled KERBEROS logging, I found below in the system event log of SQL Server machine (Computer B in your example) :
1. STATUS_ACCESS_DENIED
2. KERB_ERROR_RESPONSE_TOO_BIG
Any help would be highly appreciated!!!!
