Thanks, I'll take a look at the MS site again. It is more the changes in admin concepts than the new client functionality that I am wanting to understand Steve -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Jeff Pitsch Sent: 06 September 2005 13:15 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Terminal services on Win2003 - key differences from Win2000 You've missed quite a bit actually. Just to clarify one thing though, license servers have never talked to other license servers. Win2k3 license servers can be on any member server as well. I have found that putting it on a DC doesn't guarantee discovery. You'll still want to set the registry key. If you go out to http://www.microsoft.com/windows2003 there will be some papers there that discuss the difference between Win2k and Win2k3 (things like client drive mappings, universal print drivers (first version in SP1), etc).

Could anyone confirm/correct me on the key differences I have read regarding terminal services on Win2003. And is there anything else important I've missed? All clients (not just downlevel) need a TS CAL to connect to Win 2003 TS server There are device TS CALS and user TS CALS. There is currently no method of assigning a TS PerUser CAL to a particular user account. Win2003 TS Licensing servers do not talk to Win2000 TS Licensing servers. A Win2003 TS will need a Win2003 TS Licensing server. Recommend installing on domain controllers (for automatic discovery) A Win2003 terminal server will allow clients to connect without a license token for 120 days or until the license server issues a license through the terminal server before it requires communication with a licensing server. This period begins the first time someone connects to the server via terminal services. Temporary licences work for 90 days. Permanent licences last for 52-89 days. A client will begin a new license request 7 days prior to the license expiration date.
