Question : Sporadic Transaction Log Backup failure

We are seeing a sporadic (as to the day it occurs but not the time) failure of our Transaction Log Backup jobs.  The failures thus far have occurred at the 10:00 am scheduled run.

The error message: Executed as user: Domain\User. 11 percent processed. [SQLSTATE 01000] (Message 3211)  21 percent processed. [SQLSTATE 01000] (Message 3211)  32 percent processed. [SQLSTATE 01000] (Message 3211)  43 percent processed. [SQLSTATE 01000] (Message 3211)  51 percent processed. [SQLSTATE 01000] (Message 3211) Write on "\\server\share\T-Log.BAK" failed: 1398(There is a time and/or date difference between the client and server.)  [SQLSTATE 42000] (Error 3202)  A nonrecoverable I/O error occurred on file "\\server\share\T-Log.BAK:" 59(An unexpected network error occurred.). [SQLSTATE 42000] (Error 3271)  BACKUP LOG is terminating abnormally. [SQLSTATE 42000] (Error 3013).  The step failed.

The database server has a System event logged as well : The Security System detected an authentication error for the server cifs/server.  The failure code from authentication protocol Kerberos was "The time at the Primary Domain Controller is different than the time at the Backup Domain Controller or member server by too large an amount.
 (0xc0000133)".

According to our SysAdmin all servers are syncing time properly and we see no difference between the servers and DC.

Thanks.

Answer : Sporadic Transaction Log Backup failure

I have since "upgraded" the SQL jobs that I scripted from SQL 2000 to Maintenance Plans in SQL 2005 and the issue has not continued to date.
