Hello Im having intermitent problems with an sql cluster server. Im getting the following errors: Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.240.145] and SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.240.145]. Any Idea in how to solve or troubleshoot this issue? Server is running on 2003 server, and the server is able to contact the domain controller with no issues. Best Regards
