Anyone ever have DHCP make itself unauthorized? What makes it dothis?

[ei8ball]

We'll get a call that a whole office can no longer get on the internet or print, etc. Come to find out they aren't getting IPs because the DHCP is now unauthorized. Anyone seen this? We authorize it then all is well. What would make it unauthorize? Any ideas? Out of say 40 sites 3 have done this in the last couple months. Any help would be greatly appreciated!!!!

Thanks!

Bump. Hard to believe no one has run into this. In the past month I have had 5 servers unauthorize themself. I get a call that a user can't access network resources and after a little investigation I realize the user has no IP and can find no dhcp server. I goto the server that is supposed to be running DHCP and it has a little red dot next to it. I authorize it and 30 seconds later we are back in business. But why and how would they unauthorize themselves. Is there something triggering this that I just haven't found yet? Anyone seen this? Give me some hope please.... You were born an original.

The only time I have seen this happen is when you introduce another DHCP server to the network, such as an internet sharing device or similar devices. The W2K DHCP automatically deactivates to prevent conflict. If the other DHCP server has been removed or deactivated, the W2K DHCP will allow you to reactivate it. There should be entries in your event log to indicate if this has been happening.

If you have any cisco routers you can always set them up to provide Dhcp
