Using a Windows 2003 server as the only license server

Are there any issues that will arise with using our new Windows 2003 Server as our only license server? Are these TS CAls transferable to a different license server if we no longer use the old server as a license server?

To answer your last question first, there is no reason why using this box as the license server should not work (a Win2K3 license server can issue Win2K TSCALs), but you will need a license server. Although a terminal server does not need to connect to a license server every time someone logs on, it will check for the license server at intervals and fail to operate if it cannot find one. That may be why the users can't log on. To transfer the TSCALs to the new server, you'll need to call the Microsoft Clearinghouse. Before calling, have your Volume License Agreement numbers or your retail product numbers handy if you can, as this will save time.
