Cannot Generate SSPI Context

My Maintenance plans stopped working this weekend and in the report, all it
says is "Cannot Generate SSPI Context". These plans were working before. I
know I've seen this before, but Can't remember how to resolve this. I've
looked at a microsoft article but couldn't make heads or tails of it. Can
anyone tell me needs to be done?
Thanks for the help!
Hello, Sam

An easy solution may be to use the Named Pipes protocol instead of
TCP/IP: run CLICONFG.EXE and make sure that Named Pipes is at the top
of the enabled protocols list (this is one of the solutions described
in KB 811899).
