Remote enable RDP on 2003 and XP

Remote desktop is not enabled by default with Windows XP and Win 2003 Server. 
However, you can connect through the network to a remote registry and enable it.
The key you need is :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
 
Change fdenyTSconnections from 1 to 0 and then remotely connect to the PC you need. 

You can also do "reg add \\[machine name]\HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server /v fdenyTSconnections /t REG_DWORD /d 0 /f"
replacing [] woth your remote machine name.


I do not need to tell you that you need admin rights on the remote machine to do this...
