I have a server running VMware ESXi 4.1.0 (free version). On this server, I have 25 Virtual PCs created with various Operating Systems. (Windows XP SP3, Vista SP2 32 & 64-Bit, and Windows 7 SP1 32 & 64-Bit). These PCs are used for loading and testing software that our developers write. The testers will take an initial Baseline snapshot of the PCs, load the software perform their testing, and then roll the snapshot back once they are ready to try another product out. This way they have a clean slate for testing.
The problem I am experiencing is that when they roll the software back, the Virtual PCs somehow lose their Active Directory Domain identity. You can no longer log them in with the AD usernames & passwords. To solve the problem, I have to log in as a local admin, add the PC back to the WORKGROUP, reboot, then re-add it to AD. Should the Snapshot not be retaining this information so I don't have to do this?
