I dont know if that VM' exist earlier, it was more than a month or so . is there a way to query the virtual center database , if a VM exists or it was renamed or it was delted ?
I'm pretty sure the guys in the PowerCLI forum will be able to help. If you want I can move this discussion to the PowerCLI forum.
You may also want to check whether http://www.virtu-al.net/2008/12/10/who-deleted-my-vm/ helps.
