Hi All,
we have active active 2008r2 cluster. for example we have A instance on Node1 and B instance on Node2. last week we fail over the B sql instance from Node2 to Node1. all resources are came online except sql services. after this we checked the event viewer and found the below errors.
1) [sqsrvres] OnlineThread: Error 435 bringing resource online.
2) Could not register Service Control Handler. Operating system error = 2310(This shared resource does not exist.).
3) Another computer has sent a name release message to this computer, probably because a duplicate name has been detected on the TCP network. The IP address of the node that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.
4) Failed to initialize
SQLSQM timer. One of the following can be the source of the problem: registry
doesn't contain all necessary information, server instance name can not be
retrieved correctly, failure during timer creation, etc
and then we google it and came to know, it's happened because of .net frame work got corrupted. we have only one way to uninstall the .net and reinstall it on problem node and then reboot the server.
but we didn't see the any other errors related to the .net corrupted in server. we didn't fail over the A instance from Node1 to Node2 and fail back from Node2 to Node1 to check it's working fine or not.
Please help me to come out from this problem.
Thanks in Advance,
rup
