Stranger error in server console

[tonedef]

The following error is printing on the server console of all developer machines, a test server and the production server. It was just noticed starting a few days ago. Has anyone seen this behavior before?

I recieved the answer on the silverstream.server-nt newsgroup, and I thought I would share it here for everyone.

This stack trace is caused by the w32.nimda.amm worm. Silverstream app server is not vulnerable to this worm, but this trace is dumped everytime the system is probed.

This error is related to Nimda virus.
You need to put a filter on your firewall to prevent it.
