I recently have been asked to work on restoring a network for a small business here in Houston. the issue that I have left that is puzzling me is VPN. They have 4 computers that connect remotely to a SBS 2003. They do this by using a verizon card in the field and then connecting though VPN. 2 computers connect fine, One i need to replace, and the 4th does not connect at all. This is a dell inspiron running windows xp. The vpn on the machine says it is connected, but the SBS server doesn't show it under remote clients. the connection was working fine until about a month ago. The VPN connection is vpn.companyname.com using windows authentication. The office network first runs through a cisco pix 501 and then to the server. The XP machine is getting a correct ip address on the VPN connection. Locally the computer connects to the network just fine. I do have wins set on the VPN connection pointing directly to the server. However the server can't be found though the VPN connection. Does anyone have any ideas?
