We currently moved our Windows Server 2008 R2 Servers with SQL Server 2005 x64 SP4 to Active Directory.
After moving the servers to Active Directory, we noticed that all of our processes that access SQL Server remotely were failing with the following error: Update: Processes are run via Task Scheduler.
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed.
Used googled and found folks resolved the issue deleting deleting duplicate SPNs using setspn. I haven't found any duplicate SPNs. Currently, we are only using NTLM not kerberos as the protocol.
As a work around, I am looking at creating a SQL Server Account and assigning it to all databases to ensure we can have the monitor working as it should until we resolve the SSPI Issue. Before I can move forward with this, I would need to contact our security folks, since we are required to use Windows Authentication.
Any assistance would be appreciated.
