Clients may receive the following error when they try to connect to aWindows NT 3.51 server:
System Error 71
No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept.
One possible cause for this error is that License Manager has not been setup to grant enough connections to meet the client's demands. In this case,go into the Control Panel's Licensing tool and set up License Manager withthe appropriate number of client licenses per seat or per server.
Another possible cause of this error message is that License Manager has acorrupted or incorrect purchase history record. The Cpl.cfg file in the%SystemRoot%\System32 directory is responsible for maintaining thisinformation.
