D,
Here's my findings thus far.
1. Still some level of STAF/Hosts file issue with Standby0, as the harness is unable to copy over all of the config files. Double check that they can each STAF Ping each other by name, both directions. 'STAF <name> ping ping' is the format. I suspect one doesn't know the hostname of the other.
2. You have your client0 on the same cluster as your workload VMs. You should have your clients and workload VMs on separate clusters/hosts.
3. OK, now on to the real problem at hand. The first thing we need to do is figure out why the canceltest operation was unable to recover a wrf file for your mailserver, and whats going on with your process. For this, log into your client0 and cd to the c:\vclient\mailserver\ directory. Go ahead and zip up all of the files in this directory and attach them to this thread.
