This just showed up in my event log with the message: "The terminal services licensing server SERVER2-DCLS has no permanent licenses for product 'Windows 2000 Terminal Services Client Access License'. Use Terminal Services Licensing administrative tool to register more licenses.

We have made no changes to our licensing and the number of users hasn't changed or anything. Any ideas

Have you checked in TS Licensing Manager which client devices have
used your TS CALs? Maybe some of your regular users have received a
new PC? If your licenses were installed prior to SP3, they will not
have an expiration date. Many of your licenses can have been issued
to now discarded clients. If that's the case, you'll have to phone
the Clearinghouse to get them reissued.
