We have a Windows 2003 cluster with 3 nodes running two SQL Server 2005 instances. They regularly report messages like this in the logs that seem to indicate network issues, can someone more knowledgeable in Windows clustering let me know:
- Are these messages 'normal' - they look very much like errors
- What are some potential causes for these errors
OS is Windows Server 2003 x64 SP2 . Sorry I don't have more details about the network its managed by an external party.
