Hi, Folks, does anyone know why XP machines are not allowed to VPN into the
domain from a specific location? They work from People's homes, but fail when
they are at the offsite location? We are leaning towards a firewall issue.
The Vista machines work fine from that delinquent location. Problem is that
the folks need to be on XP for application reasons.


Thanks
 
Is port 443 blocked? Turn the useless Windows Firewall off for a start

Do you have terminal services & the required CAL's in place? Does the VPN
box allow that number of connections?

Are they members of the required groups like Remote Desktop..?

Do the XP machines get a certificate error like Vista machines do when an
untrusted certificate is installed?

Is the exteral IP correct?

Many questions unanswered
