I have a Groupwise email server running on an IBM eServer xSeries220. After installing SP7, the LSL.NLM hangs. Now when I F8 into maintenance mode, it runs all the way thru and hangs at "Processing Stage 1 loading NLMs -Scanning for Devices and Partitions."

I can't get into NWconfig. How can I get the machine to where I can roll back the install? I would appreciate your help.
