I am preparing to build a Windows 2008 R2 server to use as a TS Licensing server. Should it be a member server or domain controller. Currently, I have a 2003 Server DC, a 2003 Exchange Server BDC role, two 2008 Servers running Remote Apps. I need to ad a licensing server since the 180 days expired for the built-in licensing for terminal services. I've already purchased the licensing but am unable to install them. The 2003 DC is currently a licensing server but there are version incompatibility issues between 2003 license server and 2008 RDP servers.
