Hello
I'm studying for the 70-290 exam, and therefore downloaded the evaluation version of Win Server 2003 R2 from microsoft.com. After installing it, I promoted it to a DC by running the configure your sever wizard from the "manage your server" page. I chose the "typical config for a first server" option.
So it installed the DHCP service, Active directory and created a domain called "contoso.coml" <- the l was a typo, but it really does not matter either way anyway.
After that I connected this computer and another computer that was running XP SP2 in a network, using a 4-ports hub. And then I joined the domain with the XP SP2 computer, and everything seemed fine, until I tried to remote control the XP SP2 computer from the win 2003 computer.
The thing is that I can ping the server from the client computer, and I can also connect to it, but I can't ping the client computer from the server, nor can I connect to it. I have not activated the evaluation version yet, but I dont think that should be a problem, because it should run with all features for 14 days.
Anyway, the client computer was receiving ip from the DHCP service, so I tried to give it a static ip, but the problem remained. Does anyone know what could be causing the problem?
All input would be appreciated.

PS Please excuse my poor english.
