I'm connecting to a Windows Server through a VPN connection. I'm able to connect to the server and look at the shares after going to Go -> Connect To Server. I enter smb\servername. However, it connects me as a guest and prevents me from viewing the contents of folders I have access rights to. When I click the "Connect As" button in Finder, it removes the server from the "Shared" section in Finder.

Does anyone have any suggestions or solutions?
