We're a small company running Windows 2000 Small Business Server (SBS) and MS Exchange on a Compaq 350 server with two 72GB drives (one is a mirror, no RAID). We've had a recurring problem with the server hanging on startup. What it will do is display the Windows 2000 startup screen. The progress bar will get exactly 3/4 of the way through (what I call the "line of death"), and will stop. It looks like it's still loading as the "progress shading" at the very bottom is still changing, but nothing is happening. Repeated reboots after about 10 minutes don't help. The only fix is to shut down and pop the mirror drive out of the bay, then restart...the server will then start. This has happened several times already. We replaced the mirror drive after the first time, and everything seemed ok for awhile, but then it happened again. Popping out the mirror drive once again fixed the problem. The mirror drive is 100% healthy according the the disk management screen. Has anybody ever heard of anything like this? Is my server just a POS? Any ideas at all would be appreciated...thanks!
