It was said that "error code 8901" indicated a license problem. For your
reference, the server has actually been installed since 2002 with 300 users
license. Until Jan 2007, ServerRAID controller on the server got a
problem. We tried to recover it and then rebuild one of HDD due to an error
might be caused by the effect of controller. After the HDD has already
restored, we start the server.. but, finally no client can login to the
server. An error code 8901 was appeared as i mentioned above.

From server console, NWCONFIG.NLM cannot be utilized for repair the novell
license. A comment of dialog box said, it must use NWADMIN32 from client PC.

My question is how to insert license code to the novell server while
NWCONFIG and NWADMIN32 is no function? pls anyone advise me.
