I am using my PDC as my DHCP server. It is assigning IP address correctly but for some reason I can't see or ping my PDC. I am able to see and ping every other computer on my subnet. Can anyone tell me why this might be happening?

This sounds very strange. When you say you can't ping the PDC, do you mean by name or by number? If you can't ping it by name then WINS is not setup and you have no name resolution. If you can't ping it by number which protocol are you using as your main protocol? I suspect that you have more than one protocol installed and that TCP/IP is not installed correctly. More information would help.

You probably don't have an LMHOSTS entry pointing to the PDC on your DHCP server (the DPC). For some reason DHCP servers don't seem able to point to themselves. Try adding an LMHOSTS entry for your PDC on your PDC. I had to do this when I used myPDC for a DHCP server. Now I use a member server.

If you don't already know, the LMHOSTS file is in the \winnt\system32\drivers\etc directory. If you don't currently have an LHMOSTS file there you will find an LMHOSTS.SAM file with sample entries to show you how to create one.

If you can't ping by IP number, I would guess that the subnet mask is set differently than that being issued to DHCP clients or that the subnet is different.
