My son is at college and his XP PC was on my domain I run at home. Even\nthough he is no longer on my network while at college (obviously), he's had\nno trouble since he has been logging in with the locally cached profile.\nHowever, he let a "buddy" try to fix a networking problem and the "buddy"\nremoved it from the domain, adding to a workgroup. Of course then he couldn't\nlog in with his domain account, though I got him past that by logging in to a\nlocal account I had previously created on it.\nBut now he's running into a bunch of errors and problems and I'm thinking\nthe only way to fix most or all of it is to get his PC back on my domain.\n\nJonathan\nHow do I add his PC back to my domain while his PC is 10 hours away at\ncollege? Can he VPN into my network and then the necessary communication will\ntake place between his PC and my DC?\nIf so, what do I need to set up on my end to allow that? Obviously opening\nports in my firewall is not a good idea. Do I set up RRAS on my DC or what?\nI've never really set up RRAS before so don't know just how that would need\nto be configured.\nAnd would I need to open any ports in the firewall to allow his PC to VPN\ninto the DC/RRAS server?
