I ordered a MCS-7835-H1 with 2048MB RAM and Two 72GB SCSI HD-1 through iProcurement-->Internal ordering. I'm not able to install Windows 2003 server - either standalone OS or with OS packaged with CUCM 4.3. The intial install seems to go through fine and after a few self initiated reboot, the system hangs at the Window 2003 Server welcome screen. I'm trying to install 2003.1.2a-H.iso image. Should I RMA the equipment ?
