I need to know how to increase the maximum color depth for a Terminal Services Client on a Windows 2000 Server.

I read the MS docs about the mmc then to addin the Global Policy and so on...

But where they say "Select Computer Configuration, click Administrative Templates, and then click Terminal Services."

Document link: http://support.microsoft.com/default.aspx?scid=kb;en-us;278502&sd=tech

I don't have Terminal Services listed. This is extremely urgent if anyone could help that would be great!

Regards.

You can't.  Windows 2000 Terminal Services only supports 256 Colors.  Regardless of RDP client.  Windows 2003 improves that and allows up to 16 bit color.  You also have to have a client that supports more than 256 colors - that can be downloaded (for 9x and NT based clients) from here:

I have seen a Windows 2000 Server running Terminal Services with a client color depth of 24bit. My clients were running the same server with a higher color depth than 256, I have just run through a reinstall and their colors have dropped, and the program they run accross the network (through TS) requires at least 16bit.

Thanks though leew.

Are you sure they weren't running Citrix, which may well support higher color depths?

What third party software did you use?

I would like to also point out that in absence of referential evidence to the contrary, my answer applies here (from my first two comments)

"You can't.  Windows 2000 Terminal Services only supports 256 Colors."

and

"Are you sure they weren't running Citrix, which may well support higher color depths?"  <-- implying 3rd party software solution

Terminal Server WILL run to the color/resolution specs of the receiving monitor/system when used via the Remote Desktop Client.  I'm haveing some very nice results with this.

DO NOT ACCEPT THIS AS THE WINNING COMMENT (or I will just have to un-accept it.)

The custom software is called "Vound Dret's Colour Depth Resolve". A local guy here wrote it. It basically adds a few extra functions into the Terminal Session.
