Hello and good time

We as a institution bought and installed Netware 5.0 in our network. For
security issues we decided to install Netshield that is McAfee's product
related to Netware servers against viruses. As mentioned in manual of
McAfee and as a requirement we must install Support Pack 6a for Netware
5.0 before installing the Netshield. The problem is here, after installing
the Support Pack 6a, users could not log in to network. As it shows we
think the problem relates to overwriting the License Service, of course
maybe but it is a possibility. How can we solve this problem?
By the way, If there are other issues during SP6a installation that may we
will face with them please tell us.

Thanks A Lot
