If this is set to 1 Windows uses the credentials of the VPN connection for all further accesses (this is contrary to the behaviour of XP).
To fix this problem:
- Locate the .pbk file that contains the entry that you dial. You can find this file in location C:\Users\Username
- Open the file in Notepad.
- Locate the following entry: UseRasCredentials=1
- Modify the entry to the following: UseRasCredentials=0
- On the File menu, click Save, and the click Exit.
