Clients hang after +/- 60 client connections

We have a domain with a single domain controller and about 75 clients.
When the first 50 computers are loged in everything works perfect.

As soon as the next computer trys to log in all computers hang. Shuting down some computers will resolve the problem.

How can I trouble shoot this problem?

    Any revealing information in the event logs when this happens?

    Off the top of my head i want to say it may be a CAL issue. Each client connecting to a server needs a license you may only have 50 licenses and when you hit that you get problems.

    Another idea but this is doubtful, is your DHCP scope large enough to hand out more than 50 ips?

    Never found the solution. Migrated the hole environment to a new one (new servers & switches and re-installed all computers)
