| Our data center was recently moved. The development servers were moved to a virtualized environment using Ghost to copy the server from the old location to the new location. Ever since the migration our virtualized development and test servers have been generating the error "Cannot generate SSPI context" when we try to connect using NT Authentication. When I switch the client to Named Pipes instead of TCP\IP, as specified by a Microsoft workaround, the NT authentication works without problem. Only the default instances are failing. The named instances on these virtualized servers work as expected.Could this problem be related to VMWare or Ghost? The consulting company who performed the migration said they verified the SPN does exist. Any suggestions.Thanks, Dave |

| Have you looked over this (http://support.microsoft.com/?id=811889) KB article? From what I gather by your error the problem is with your DNS or Active Directory. Maybe it's different due to the move?DanielSQL Server DBAwww.dallasteam.com |

| Yes. I've seen it. Our consultant was to check the SPN, but I'm not sure if he did. When I try to run SETSPN -L servername I receive ldap_search_s failed: No Such Object. Not sure what I am doing wrong.I just changed the port from 1433 to a different port and it worked. There must be some type of contention with that port. The strange thing is the non-virtualized (stand-alone) servers use 1433 and experience no problems.Thanks, Dave |

When I can, I always change the port to something other than the default 1433. It doesn't really matter if you're behind a firewall but I still like to do it. DanielSQL Server DBAwww.dallasteam.com |

| Are you using ESX or GSX for vmware? I have had this problem twice but on standalone boxes not in the VMware world yet. I did the same thing you did to fix. We did have a problem with MSDE about the vmtools back reving a shared dll and MSDE would not start. Thanks Frank |

| I'm fairly certain they setup ESX. |
