UPDATE:I disabled the VMware tools service last night and it still happened. I believe the C:\work directory, which is a share that is actually the E: drive mounted as a directory to C:\work is being accessed by 2 remote hosts simultaneously and perhaps this is causing a lock on the directory by the first host. This did not used to happen before I mounted the E: to the work directory,, Are there any known issues with file locking and volumes mounted as directories?
