for some reason I cannot ping any device on the internal network but I can ping the host-name.
DHCP and DNS are running off the server.
Its a 2008  r2 server.
We have a router attached to a switch which all the devices and server are attached to.
DHCP is not running on the router.

Have you confirmed that the ip-address that the ping host-name is returning is the same?

interesting.
Have you tried pinging from another machine to see if you get the same results?

im not onsite right now but i looked it up and IPV6 takes presidence over ipv4 when you ping localhost.
but the issue still remains that i cant ping ipv4 addresses
it should still ping.
when i installed a new printer on the network i had to use the hostname for the pc to see the printer. it would not see the IPv4 address. I even used a static ip on the printer too.
it seems that something is blocking IPV4. just dont know what it is

Initial guess: IPv4 addressing is not working (DHCP stopped, misconfigured, etc) and IPv6 works as it uses SLAAC.
Can you post a few screenshots/outputs trying to ping by name and by v4 and v6 address?
