More than likely, you are having problems because there is something running or installed on the server that the database install utility is conflicting with. I had the same problem installing SCCS 4.2 on a Compq Proliant and it ended up being the Compaq SmartStart server utilities that were the problem. In theory, they shouldn't have conflicted; but Nortel software doesn't play well with others. The server needs to be as clean as possible with Windows 2000 Standard server, and then only SNMP installed in the windows components section.
