I'm on Vista and am trying to connect to my company's network from offsite. I've installed their VPN client and logged on successfully. However, I don't have access to the intranet through the web browser and none of the network resources are showing in Windows Explorer. When I try accessing the intranet, I get a Windows prompt. I sign in with my credentials but it just continues to prompt me. Is there something else I need to gain access to resources?
