I check the SPN of SQL and WFE as below. Is that correct for proper functioning of SharePoint? Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:\Users\spsservice> setspn -l sql01 Registered ServicePrincipalNames for CN=SQL01,CN=Computers,DC=virtualdomain,DC=v net: MSSQLSvc/sql01.virtualdomain.vnet:53976 MSSQLSvc/sql01.virtualdomain.vnet:SSRS WSMAN/sql01 WSMAN/sql01.virtualdomain.vnet RestrictedKrbHost/SQL01 HOST/SQL01 RestrictedKrbHost/SQL01.virtualdomain.vnet HOST/SQL01.virtualdomain.vnet C:\Users\spsservice>setspn -l spswfe01 Registered ServicePrincipalNames for CN=SPSWFE01,CN=Computers,DC=virtualdomain,D C=vnet: TERMSRV/SPSWFE01 TERMSRV/spswfe01.virtualdomain.vnet WSMAN/SPSWFE01 WSMAN/SPSWFE01.virtualdomain.vnet RestrictedKrbHost/SPSWFE01 HOST/SPSWFE01 RestrictedKrbHost/SPSWFE01.virtualdomain.vnet HOST/SPSWFE01.virtualdomain.vnet

Hi, Thanks to share your post. For the issue, I think you may need to learn the details of the setspn command: http://technet.microsoft.com/en-us/library/cc773257(WS.10).aspx. Hope this could help you! Leo
