Can't ping my WinXP clients (DHCP) from my DC

March 14, 2011 at 13:43:33
Specs: Windows Server 2003 R2, Intel Xeon X3220 2.4GHZ
I've recently been unable to ping my WinXP SP3 Clients (DHCP) from my DC (WinServer2003 R2).

My WinXP Clients get their DHCP Address from a DHCP server, which i don't manage. However, my DC is on the same subnet as the DHCP server.

Is there a recommended configuration of WinXP clients using DHCP for their IP addresses but my DC as their controller?

Thanks

You simply go into the NIC's TCP/IP stack and set it to automatic. The driver does the rest utilizing the DHCP protocol. Here is more on how it works...

As for you not being able to ping it, there is either a firewall, its down or you are are pinging the wrong address. I would talk with the person who does administer the DHCP to find out.

The only recommendation concerning your configuration is that the workstations dns entry points to the DC for dns.

Otherwise you not being able to ping a workstation has nothing to do with the fact the xp boxes are getting dhcp ips.

The unfortunate issue with this setup is the AD DNS server is never updated by its dhcp server so you can't just ping by name.

Thanks for the help Ace! I already have my NICs TCP/IP setting to use DHCP and have the DHCP server specified as one of the DNS servers.

As for the pinging; I doubt it's a firewall issue as I'm on the same subnet as the DHCP server. I'll double check that I'm using the correct IP and get back to you.

It feels more of an issue regarding my DNS records not being up to date w/ the ip addresses of my clients and their corresponding host names.

Thanks for the help wanderer! My workstations dns entry does point to my DC for dns.

I see. I'll try pinging by IP and let you know my results, but i think you're right regarding my set up. I need to speak w/ the DHCP admin to see if i can't get his DHCP server to update my AD DNS one.

The test would be ping by name not ip. By name requires dns to resolve the name whereas ping by ip does not require dns.
