Ok so iv'e made a visio to assist with this troubleshooting. So heres whats going on. The server test.com is set up to be a dhcp and dns server. the router has DHCP disabled as to allow the server to distribute the ip addreses. Computer B can be added to the domain with test.com with no problems and successfully obtains an address from the DHCP server. Both computers have their ip/networking settings exactly the same.

Computer A  cannot find the domain test.com
I have tried discconecting the " To other server/internet" connection before and i still cannot find the domain


So from this diagram and information what is the best guess as to why computer A cannot find the domain?

Post the results of a ipconfig /all from both A and B hosts for review.

 

Off the top it appears the server is on the wrong side of the router.  Did you enable dhcp relay on the router?

How is server Test.com connected to the router? (LAN or WAN port)

 

Can Computer A ping, Computer B? Router? Test.com?

Ok so so computer B can ping computer A and the server

Computer A cannot ping computer B also cannot ping the server

i do have a good lead at this point as i missed the important detail that switch 2 is connected to the router via the WAN port which is most likely why its not functioning the way i need it to and then switch 2 is also connected to switch 3 and of course switch 3 is connected to
Computer B thanks for the help.

 

i will edit this post if i cannot solve the issue with these details

 

and yes you were right lol the server is on the wrong side in the diagram

 

diagram corrections
