I'm currently setting up a remote user with a Cisco 871W connecting using ezvpn to a ASA 5505 at the main site. I've basically got this working fine, the VPN connects automatically when it's switched on and I can ping all networks.
The trouble that I'm having is that laptops and PC's on the remote side aren't able to authenticate against the DC's, located in the main site. If I try to add a laptop to the domain from the remote site I get the message: An Active Directory Domain Controller (AD DC) for the domain could not be contacted.
Should I be doing anything on either side to resolve this?
