From the onsite computer run Regedit.

In Regedit:
File-->Connect Network Registry

In the 'Select Computer' dialogue make sure that the 'Look In' location is correct(should be your domain if applicable)type in the computer name or IP that you want to connect to then click Ok.

Now expand:
<computername>HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server

Once you've opened that key look for fDenyTSConnection

Set it to a value of 0 <--a zero

The computer will have to restart for the change to take effect.

Try this. I have had to do this sometimes.

If there is a user at the remote computer you can get connected using join.me and then enable it yourself.

Use this script. Works wonders

I think you have all ready been pointed the right way, there are script that will enable RDP on a system as long as you have remote registry access. It looks like a couple of people have pointed you to scripts all ready.

trying the script but it says "make sure you type the right machine name" i have and doesn't work..tried IP, name and nothing

did you run the script from your PC at home or the server that you are RDPed into?

Yea from remote location.

is it possible the computer is off or in sleep mode? Can you ping it?

yep it pings.

seems as there's no way i can get to this.

The registry edit didn't work? What were the results when you tried?
Were you able to get to it's registry?

I was able to type the IP and it took me to the enter username and password. I inserted the right username and password and nothing.

I was able to use the script just fine to my window servers by simply inserting the IP and it gave me the option to enable and disable, but the problem is i am trying to get to a desktop in the office it just doesn't work. I was able to get a ping from the adress.

so the script works on the servers, you can ping the desktop which proves connectivity, you can run regedit on the desktop but cant authenticate...

do you have admin rights to the desktop?

I just found out the desktop is not on the domaincontroller, but can still ping..would that have something to do with it?

Most definitely wold change the permissions required.

If the desktop is not on the domain you would need to enter local admin credentials when connecting to the remote registry.

Might need tobe in the format of PCName\LocalUsername & Password.

I have also seen where strangely there were no users in the remote desktop group(including local and domain admins), never was too sure the how or why that one occured i just added them into the group and it worked fine afterwards. another thing is the firewalls may be causing blockages check those settings remotely as well for both port and program access

I created this a long time age:
