NT Server 4.0 hangs at login

[albracco]

NT 4.0 server had been running fine, suddenly nobody could connect to it. Rebooted server, gets to login prompt, go ahead and login, but it just hangs there (logging on...). They can ping it by name or IP from other machines, but can not browse to it or connect to it (\\servername) That's as much as I know right now - will be going there shortly. Any initial ideas?

TIA

More info-- After trying every type of repair option known to man, did a parallel install of NT 4.0. I can boot into the new install, but I don't see the logical drives on a RAID 5 array. I see the two logical drives on the RAID 1 array it boots from just fine. This is an HP NETRAID adapter. Running the HP array software shows both arrays as being "optimal". Running disk administrator shows the missing drives, but it shows filesystem type as unknown. Assigning a drive letter does nothing.

ANy ideas why the new install doesn't see all of the logical drives?
