I've tested VMware Server 2 on several machines and had to go back to VMware Server 1 because of this issue:
I create a CIFS datastore using a Windows file share, then add some virtual machines to the inventory from that datastore. They behave perfectly fine and there don't seem to be any issues. When I reboot the machine, the datastore now shows 10 or 12 digit numbers for used space and free space, none of the virtual machines are accessible, and the only thing I can do with the datastore is refresh it or delete it.
Any ideas?
