We have a perfectly functioning and replicating namespace that is accessible fine from inside the network and all sites. We have three sites. Head office with a SBS2003R2 Box and a W2K3R2 Box (Namespace server1) Site 2 with a W2K3R2 Box (Namespace server2) and site 3 with aW2K3R3 Box (Namespace server3).
When a remote user connects to the network using the "connect to small business server" tool (PPTP VPN), all of the mapped drives which resolve to the namespace are visable but cannot be accessed by the user.
I'm wondering if required ports are being blocked in the SBS (RRAS) firewall

Any other ideas? Anyone seen this before??
