Cannot Ping my Workstation

[Sam3]

Could somebody help me. I have a setup here i have a firewall which is running at IPCOP and it distribute the IP address. and i have created a Windows 2003 server for the Active Directory and a DNS but im new to this one i just follow the manual. well my problem now is i have my workstation connected to my domain and i can ping the server but when im in my server and trying to ping my workstation it always shows a RTO. what could be the problem?

do IPCONFIG in dos on the client....make sure that it has actually been assigned the correct IP for the DNS..

First test...

Set the IP manually to an address in the same subnet as the Server

Server 192.168.10.1/24 (255.255.255.0)
WS 192.168.10.11/24

then try pinging each machine, if you can do it then, at least you know you have a deeper problem.

Then make sure that your DNS is both Authorised and Active (You need to Activate to turn on the scope) and (You need to Authorise to allow it to publish the addresses).

Once you have done that...on the client.
Set IP back to "automatically assign IP", open command

ipconfig /release

releases the IP
then

ipconfig

check that is now says 0.0.0.0
then

ipconfig /renew

gets new IP
then again, normal IPConfig, to check it its dns assigned.

Hope this Helps.

I've also had trouble when the Workstation has the firewall on.

yes, if the firewall is on, you also can not ping, with disabling it, or filtering through ICMP ECHO packets

Hope this Helps.
