I'm running on 2008 Server x64, using vmware Server 2 RC1.
I was able to login to the web ui ONCE -- I tried to start my virtual machine and the whole 2K8 box rebooted and after reboot I was unable to login to the web UI -- the VMware Host Agent Service keeps dying.
I have tried multiple uninstalls/reinstalls, including deletion of license and folders.
The box itself is stable, haven't had issues with anything but vmware...
I have the same issue with RC1 and RC2. I couldn't find a solution yet
