Both of our windows 7 users are unable to grab an IP address from server 2003. These two windows 7 clients have been working fine for 6 months and suddently it doesn't work anymore today. I have tried system restore that didn't help either. The error I am seeing on the windows 2003 DHCP Bad address. I have also tried assigning an static IP to the windows 7 clients but still no connectivity. No pinging reply. Please help!
