Terminal service requirements

G

Guest

I am thinking of deploying an application in Terminal Service and would like
to find out what I will need in terms of licensing and server installation,
and how many users can connect to a terminal service at a time on each
server? Is there a difference in running in W2K and W2003 servers?

What is the difference between running Terminal Service and Citrix?

Thanks
Emma

Well you asked a few questions, so let me try to address each individually.

1. For the Terminal Server you'll need one Windows Server License (2000 or
2003)
2. For the clients connecting to the TS you'll need a Windows CAL and a
Terminal Server CAL (TSCAL). Windows 2000 & XP Pro Clients connecting to a
2000 Terminal Server receive a grace connection from the Terminal Services
Licensing Service, meaning you don't ned to purchase one in this instance.

3. How many users can connect (concurrently) depends on:
A. Hardware, i.e. single or dual CPU, amount of RAM, speed of disk subsystem
B. Waht resources your app requires, i.e. how much RAM, CPU Time, Disk Time,
Bandwidth
C. Bandwidth, i.e. if users will be connecting over a WAN connection users
will need a bare minimum of 26.4Kbps per session, + an additional 4Kbps for
each increase of screen resolution, color depth, adding sound... + printing
& file copy/paste bandwidth. Unually 56-128Kbps per session is sufficient,
inless using streaming video (not recommended) or photo editing software.

4. 2003 has added features of the core-OS, i.e. cmd line utilities, group
policy enhancements... TS specific enhancements are color depth greater than
8 bit (256 colors), as 2003 can support 16 & 32 bit color depth RDP clients,
whereas this is only possible with the addition of Citrix Presentation Server
on 2000. 2003 TS also supports basic audio and enterprise edition supports
participation with session directory.

5. Citrix Presentation Server has lots of added features that do NOT come
built-into TS, i.e. intelligent load balancing, application publishing,
secure SSL Gateway, Web Interface, Universal Printer Driver, multi-multi
shadowing, policy-based control of session settings, bandwidth throttling,
TWAIN Redirection, seamless windows applications, Java Client, Central
Management Console... If you're deploying many servers, Citrix is usually
recommended, as managing a large TS farm w/o Citrix (or other add-ons) is a
PITA.

Thanks Patrick for the information you provided. It is very helpful. I am
somewhat more confused after reading all the licensing requirements for
deploying TS in application mode. I am trying to answer/clarify the following
questions:

1. I already have Win2K server License. Do I need a separate TS License if I
deploy in application mode?
2. Do I need Win2K CAL for each user accessing the TS? Yes?
3. Since users are running Win2K and WinXP Pro, I am assuming that I do not
need TS CAL, right?
4. Are there any other licensing requirements that I am missing?

I will also be running the License Server and the Terminal Services on the
same server.

I have a Win2K server that I want to run Terminal Service on in Application
mode. I also have about 25 users that will be connecting to the server. The
users are Win2K and WinXP Pro.


Thanks
Emma
