DHCP losing confi on one scope MandG <gscanga[ at ]gmail.com> 6/7/2007 5:32:28 PM I know this is a DNS forum but I also know that you guys are smart. My question is with DHCP. I have several scopes defined but am suffering from a bizarre issue with only one of the scopes- at least 4 times in the past month this scope has lost its configuration. Thus, users et an ip address but no other settings such as dns or a default gateway. I simply go back in and add the configuration to the scope but I want to know what's causing this? Does it makes sense to suspect that the switch in the idf closet could be canceling out my DHCP servers configuration? As this only happens to this same scope.

Possibly a virus or a malicious user with Admin rights? I've never heard of a virus that does this, but these days you can never tell what some malicious hackers will try. There are group Policies that will override these DHCP options on the clients, but I still don't think it would change the set options on the scope itself.

Re: DHCP losing confi on one scope MandG <gscanga[ at ]gmail.com> 6/12/2007 2:37:30 AM Thanks for the tip about the gpo, Kevin. Just for the heck of it, I've deleted the scope and re-configured it again. We'll see if it holds up. Thanks!
