I was browsing through event veiwer and came accross this error under the system tab,
Unable to contact a DHCP server. The Automatic Private IP Address 169.254.57.132 will be assigned to dial-in clients. Clients may be unable to access resources on the network.
I have also noticed that once an IP address is changed on one of the computers (for example network cable unpluged and pluged into a router to configure it) when the network cable is pluged back into the computer (for the main network) the DHCP server on SBS is not contactable and the NIC assigns itself the ip address above 169.254.57.132
Has anyone come accross this issue before?
