I have been running a machine for 3 weeks without any issues whatsoever. Suddenly today when a laptop decided it was time to re-connect to the network, it could not retrieve an IP address.
I am running an SBS2003 machine and had it as the DHCP server. There are no other DHCP servers on the network apart from a wireless router which has the option disabled. THe strange thing is that it only happened yesterday/today so I am not sure what is going on.
I have tried the following:
1. REstarting the DHCP server
2. Restarting the Server
3. Re-creating the DHCP scope
4. Unauthorizing and re-authorizing with Active Directory.
For some reason the computer just cannot get an IP. All machines can ping the server (those with static IPs) and if I enable the wireless router as the DHCP server instead of the SBS2003 all computers get an IP and can also ping the server.
Please let me know of any ideas!
