Checking MS SQL Server with SNMP

Hi all

I try to check my Microsoft SQL Server 2000 with a SNMP Query. But I always get the Message no such name (1) as Problem. The Probe looks like this:
OID: iso.org.dod.internet.private.enterprises.microsoft.software.apps.mssqlServer.mssqlServerObjects.mssqlSrvTable.mssqlSrvEntry.mssqlSrvState.21.77.105.99.114.111.115.111.102.116.32.67.111.114.112.111.114.97.116.105.111.110
OID Type: integer
Compare Method: ==
Integer Value: 1

I also tried the OID: iso.org.dod.internet.private.enterprises.microsoft.software.apps.mssqlServer.mssqlServerObjects.mssqlSrvTable.mssqlSrvEntry.mssqlSrvState

If I try the SNMP walk I can navigate to the Value and I also can automaticaly create a probe. However the result is always no such name (1)

Has anybody an idea on how to check wether an SQL Server is running or not (I don’t want to querry the port 1433)

Thanks for your help
