Question : Server can ping client, but client cant ping server
|
|
Scenario:
Windows 2003 server (IP10.0.0.100, gateway 10.0.0.138, mask 255.0.0.0) running DHCP (scope 10.0.0.1 10.0.0.254), DNS and Active Directory
Modem/Router SpeddTouch 510 (not 510i) (IP10.0.0.138) with DHCP and DNS turned off, working as gateway.
Windows XP client (IP10.0.0.50, gateway 10.0.0.138, mask 255.0.0.0)
Issue:
The server can ping the client (using both IP and name), but the client cant ping the server (using neither IP nor name).
The clients network values were entered manually because it wasnt able to get them from the 2003 server. This IP address (10.0.0.50) is not being used (therere only two machines connected to the network, the server and the client)

I understand you upgraded to xpsp2, which replace icf with windows firewall. Well, if you go to netboard properties you can see the state of the windows firewall, usually disabled in local networks.
Let's see other parametters, if you can change them.
Go to servers nic and make sure its addresss is fixed, the recommendation are:
server: 10.0.0.1
gateway: 10.0.0.254
Now reconfigure the dhcp scope from 10.0.0.10 to 10.0.0.250, maybe you'll have sometimes other equipments with fixed addresses, like network printers, manageable switches... or others.
Configure the dhcp to give the workstations the new dns address, and the new gateway address. If you use a switch, it is very important to configure all the ports connected to dhcp workstation to fast port, disabling the STP. STP is not necessary in a dhcp environment,
