I have a Windows 2008 server with 1 DHCP Scope 10.0.0.X/255.255.255.0 and watchguard firebox for my internet router.
I have run out of IP addresses. I added a second scope to my DHCP server, and I can get correct IP's and internet access. The problem is I can only ping servers and not workstations. I use windows as the DNS server as well, and the entries all show up correctly as far as I can see.
Can someone help me with where to begin troubleshooting?

You need to change the subnet on your computers from a /24 to a /23. 255.255.254.0. On computers that have static addresses, such as your servers, you'll need to do it by hand.
