How can multiple Diagnostic Console users share Server Connections and custom settings.
Configuring Shared Connections.
To Share Connection Information
Note: On Server 2008 R2 and Server 2012 do not create the shared connection directory in the Program Files (x86) directory as these file could be virtualized and only available to the currently logged on user. If you have created the shared connection folder in the program files directory you can copy the contents to a new folder outside of the Program Files directory. You can find the virtualized files in the following location. "C:\Users\Logged on User\AppData\Local\VirtualStore\Program Files (x86)"
To share configuration changes between users you can configure templates.
