Error 0x8007007f: A problem is preventing Windows from accurately checking the license for this computer

I got this error, when I tried to log in to one of my Domain Controllers this morning. It is a Windows 2003 x64 server. I had remotely applied SP2 and some other patches.
 
Looking up this error, I found references to the fact that SP2 may have been installed, but the computer had not been rebooted. Duh!
 
Rebooted the server, and all was well.

Using Dual Monitors in Terminal Services with Remote Desktop

How to obtain dual monitor mode within Terminal Services when connecting with Remote Desktop.
 
The prerequisites are Remote Desktop Connection client version 6.0 or higher. Windows XP and 2003 users can obtain the client here – http://www.microsoft.com/Downloads/details.aspx?familyid=6E1EC93D-BDBD-4983-92F7-479E088570AD&displaylang=en
Windows Vista and 2008 user already have this version.
 
Obviously, you would already have two or more monitors. Some rules are:
  • The monitors must be the same resolution
  • The total resolution must not exceed 4096 x 2048
  • The top left monitor must be primary
  • The monitors must be horizontally oriented

From the start menu, open a Run dialog. Type in mstsc /span /v:servername

Optionally, you can also use the /w:HorizontalResInPixels /h:VerticalResInPixels switches.
