I have a 3-node MNS cluster running Server 2003 and SQL 2000. SQL 2000 is set up and working to a point. When I schedule Jobs sometimes they fail and sometime they succeed. I have narrowed it down by running the jobs every 1 to 5 min. If I have a DB the size of 5 Meg the Jobs complete successfully most of the time, about every 4 to 5 hours I get 1 failure. On larger databases, approx. 30 to 40 Meg, it sporadically fails. On databases larger than 40 meg it fails continually. I have also watched the folder were the backup is to be placed and I see the file created with a size of 0Kb and then it disappears. I have found a couple of knowledgebase articles but none seem to fit. In the Job History I get the following. Executed as user: (DomainUser). sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed. In the Maintenance Plan History I get one of 2 things 1. Primary [Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 3201: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open backup device 'T:MSSQL$TEST1BACKUPInventory2Inventory2_tlog_200408171140.TRN'.
