I have a Windows 2000 server running as a domain controller for an organization with about 30 Windows XP Pro PC's. A couple of these are linux boxes. I also have several printers hanging off this server via jetdirect print servers that have reserved IP's. Printing has been fine since the printers were set up a couple of years ago.
Periodically, several times a day. A random PC will stop printing. It will loose all connectivity to the printer resources on the server. File access is fine, network access as well, just none of the printers attached to the server can be communicated with. Other users can print fine, and the server can print a test page.

At about the same time, actually a few days before a couple of users complained that to access a network share on the server they would have to reboot.
What's changed in the past two weeks?
My ISP changed DNS servers so I had to make new DNS entries on the server to allow internet access. The Domain controller is also our DNS server.
I've run ipconfig /release /renew /flushdns, restarted the print spooler, restarted dhcp, and none of these seem to work. I'm wondering if this isn't some sort of infection that's gotten past the AV software and the Sonicwall. At any rate, any help is appreciated.
