Every morning it seems that our DNS servers fail. This problem is somehow related to the Sophos (sweep) scanning process that mangles with DNS (named) files. Attempts at troubleshooting this issue with Novell and Sophos has always resulted in them pointing fingers at one another.

I was wondering if there was a DOS utility (that could be called in a script) that would allow me to execute commands on our servers to reload NAMED and SWEEP? I have already written a script that calls nslookup to test our DNS servers' internal resolution, it would be great if I could add a line that restarts the services if a fail is detected.
