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

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

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?
