Q. Which file is locked on the file share witness with a Windows Server 2008 failover cluster?

A. In the event the file share witness is enabling quorum to be made, the witness.log file is locked by the cluster computer account. You can see an example of this behavior by running a net file command on the server that hosts the file share witness for a cluster, like this:

C:\>net file

ID         Path                     User name            # Locks

----------------------------------------------------------------
1677722253 E:\fsw\...\Witness.log   savdalclus$          0
1677722256 E:\fsw\...               savdalclus$          0
The command completed successfully.

Note that if the file share witness isn’t required to make quorum, then the witness.log file isn’t locked.
