Service receives following error:
SSPI handshake failed with error code 0x80090311 while establishing a connection with integrated security; the connection has been closed. [CLIENT: 10.x.x.x]
Security event log shows Authentication Package: NTLM. User is NT AUTHORITY\SYSTEM.
Error code equates to SEC_E_NO_AUTHENTICATING_AUTHORITY, which is returned by SSPI InitializeSecurityContext (NTLM), documented as:
No authority could be contacted for authentication. The domain name of the authenticating party could be wrong, the domain could be unreachable, or there might have been a trust relationship failure.
But the error occurs only intermittently, and there have been no configuration or code changes since this started to occur during current interactive day. No general problems with AD DC availability.
Seen this before? Any thoughts?
This is not a SQL issue. There are probably some network issue on your system and you lost the connectivity to AD from time to time. Please let your network administror investigate any possible network issue. Thanks.
