Hi,
Thanks for looking into my question.
I am getting this error in the SQL Server logs.
06/12/2012 10:00:37,Logon,Unknown,Login failed for user 'sa'. Reason: Password validation failed with an infrastructure error. Check for previous errors.
06/12/2012 10:00:37,Logon,Unknown,Error: 18456<c/> Severity: 14<c/> State: 10.
When I google it, It says about "Service Principal Names".
Have any of you face this kind of error before..? Please help.
Thanks!
Siva.

The error message says to look for previous errors, are there any in the error logs prior to this error?

the first link i got whens earching for the error took me here:

http://social.msdn.microsoft.com/Forums/eu/sqldatabaseengine/thread/214b0b8f-ab78-4ab1-bd73-3eeee0c8999a

it seems to imply there is something wrong with "corruption of Server Principal Name(SPN)."

can you look at that and see if it applies?
