NT Server Slowdown

By slkramer ·
I have a public library client with a single domain network with PII-233 server running NT 4.0 SP 6, and 9 clients running a mixture of W98/Me. The server has a 4gb hd with about 2gb free, and 128MB RAM. The system has been fine for nearly 5 years, used primarily for circulation software and patron internet access thru CAT 5 ethernet and DSL modem & router.

Suddenly, about 10 days ago, any applications run from the server go extremely slow, with discernible video refreshes, as if the memorywere very low. But the resources seem to be OK when I check. The card catalog software is very slow running from the server, but it runs normally from any of the workstations, which all must access the server to run the catalog. The DSL internet runs quite slowly on the server, but normally on the clients.

The tape backup which used to run about 2 hrs now takes up to 6 or 7 hours.

Panda Antivirus Corporate is running on the server, and operates properly. No new software has been installed, and I can't see any source of the problem.

Any ideas?

NT Server Slowdown

Hate to answer with more questions but...

What % of processor time is being used, and by what applications? And what amount of the pagefile is being used?

Also, how many "open" network connections to this server are there?

If a single process is eating a lot of cpu time and is not critical just end the process. If it's a critical process try restarting the server and see if that resolves the amount being used.

Your first question reminded me of something I had noticed in passing, but hadn't followed up on. The Antivirus engine was consuming 98% of the processor time. When I stopped the antivirus service, the total cpu usage dropped from 100% to 4%. I checked with Panda Antivirus Software, who told me they had made some slight changes in the signature files which required an update to the Panda Administrator and Antivirus program. I made the updates and it now is back to normal.
Thanks.
