How to fix “Device Manager is running in read-only mode because you are running it on a remote computer” on Microsoft Windows Server 2008 R2


On my laptop I run dual OS. Windows 7 for daily use, and Windows 2008 R2 for trainer preparation, because the new MOC courses are based on Hyper-V.

Then one day, when I started the Server manager it showed me this message:


I tried to search the net, but found no answers, so I started to investigate it myself.

I had given my computer the name: CTJGSWINSRV2008R2

This name is more than 15 characters, which is the maximum supported in NetBIOS. I wouldn’t think this would be a problem, but when I looked a servermanager something hit me:


The computer name is not complete! It is the short NetBIOS version!.

So I tried to change the name to something shorter than 15 characters:


and everything worked !!

Afterwards I installed Service Pack 1, and tested to see if the error was gone, but it is not.

    I was searching for a way to use the device manager remotely so that I could update drivers, change hardware, etc without command line tools. I didn’t know about the 15 character limit though!

    I ended up enabling Concurrent RDP so that I can at least login to use it without logging out any of my staff members.

    Here is how I did it:

    With a design that resembles a hatchback car,
    this model is perfect for people that want a new age caravan.
     The metal frame has rubber pads, to prevent your caravan from being scratched.

    As a location for the static caravan, Gatebeck is nestled in
    the semi-woodland location amidst unspoilt countryside and quiet country lanes making
    it an ideal choice if you want somewhere scenic and peaceful.
