Here’s a problem that has been plaguing me for some time and I can’t figure out what the problem is or where to start looking.
My network has DHCP served to it via our SonicWall firewall. Our DNS server is running on a Windows 2000 machine.
Sporadically throughout the day random users (all running Windows XP) will suddenly be unable to resolve local server names. Going to their machines, I can see that they have all the appropriate information (IP Address, DNS, Gateway, etc.) However, I have to release their IP address and renew it to fix the problem.
We recently upgraded our SonicWall hardware, however the problem persists. If I “hard-code” an IP address to a machine, the problem goes away.
I’m not sure where the problem lies…with the DHCP server or the DNS Server…or perhaps I’m missing something else?
