I have a reoccuring problem with one of my NT 4.0 servers. When browsing the network, I try to select a user computer. I recieve a message "the name limit for the local computer network adaptor card was exceeded".
Unfortunately this stoppes my backups from occuring at night, and task manager shows the processor is at 100%. If I shut down and restart it clears up for 3 days and then comes back again. Technet had no information.

Does your network use WINS?

by leo.valmores

You have not mentioned which service is grabbing the 100% attention. If you know the service that caused this, then maybe you can work out backwards. Or you can setup performance monitoring of selected services.

Also, I suspect of a malfuntioningNIC card.

Good luck

WINS leases names for a default of 6 days. At one half the lease time WINS will verify that the name and IP address is still valid and in use (every 3 days). WINS only releases name leases IF the user logs off correctly. I'm not sure how or why but I would bet that your problem is related to these facts. Check your LMHOST file also.

I really do not think WINS could be causing the problem. Possibly a faulty NIC, but if the problem is reproducable, it's probably software. Possibly a bad NIC driver. Try uninstalling the NIC, reapply the service pack, then reinstall the NIC withthe current drivers. I would then reapply the service pack, and don't replace any drivers. What kind of server? Any event messages. Perfmon is a good idea, set the interval time to a reasonable amount though or you'll bog the server. I would not waste the time. Install a different NIC as a test.
