Error Message:

Make sure connection type or network adapter settings are unique. These settings were changed, possibly by another instance of this program.

Explanation:

This message indicates that an error occurred while creating a new connection. The most common cause is two people using Terminal Services at the same time to create a new connection with the same name. The other personÆs new connection was completed before yours and took precedence.

User Action:

Back up in the Terminal Services Connection Wizard and rename your connection.
