On Windows 8, Remote desktop connection manager has the annoying habit of throwing unexplainable error messages after opening more than a couple of connections, with error code 3334
If you are managing dozens of development (or live) environments, this is bloody annoying.
I have seen several proposed solutions on the net for this problem, this is the one that worked for everyone in our office, but as always, your mileage may vary.
- Open a Visual Studio Command Prompt with Administrative priviliges
- cd "c:\Program Files (x86)\Remote Desktop Connection Manager"
- editbin /LARGEADDRESSAWARE rdcman.exe
After this (at least for us), rdcman just works like it's supposed to.
