I have encountered a problem with my SBS this morning where one of the address leases keeps renaming itself to BAD_ADDRESS.
We are a small company and have a range of IPs from a central router owned and controlled by the business centre which have access to the internet. These are 10.50.51.2-6 and the SBS is on 10.50.51.1.
It is 10.50.51.3 which keeps coming up as BAD_ADDRESS. The PC that it was affecting, I swapped the IP with another which is rarely used and now this one has the problem.
All I do is make the reservation and then enable the NIC on the client and it goes BAD.
Yesterday I had to change the DNS address on the server so I ran the internet/email wizard - this is the only change. Other than that the DHCP reservation and leases have been working perfectly for over 3 years!
I would appreciate any input for a solution to this.
