I'm having some sudden trouble with client PCs dropping their IP address. Seems that the PC requests a new lease over and over, the server responds but the PC doesn't get the lease renewal.


For example, this client requested a new lease but failed to get it. After it lost the IP completely, it THEN successfully got a new lease on the same IP addresss:

I've got my lease time set for one hour for debugging purposes. It seems that every hour almost all of my PCs are dropping their IP address. I don't think I've changed anything.

Can someone point me to some documentation that explains what the exit codes and other information means?

Thanks, Brian
