RDP (more than two connections) in Windows Server Domain

I have a domain consisting of 2003 Server OS's , Workers VPN into the domain and then use RDP (MS Remote Desktop) to access the server they wish to develop on. The issues is we can only have two connections at a time on each server. How can i increase this? who much does it cost?

You need to enable Terminal Services in Application Mode and purchase Terminal Services Client Access Licenses (CALs).  I believe the cost about $85 each, but I'm not certain.  Contact a reseller and tell them you need Terminal Services CALs (Remote Desktop Services CALs; the name changed in 2008 R2 and it's possible you'll need to buy those instead and use downgrade rights).

Also, CONFIRM any licensing questions with Microsoft Licensing and Presales Support.  Information provided here is a best efforts and may not be completely accurate, especially in regards to licensing.  "They told me on Experts-Exchange" will not be a valid defense in an audit.

Agreed...

Licensing is a slippery slope for advice. I would definitely consult MS reseller. I use CDW or Sarcom and always get good response. When you update your license you will be allowed more simultaneous connections.

one trick you can use is /console to get 3 connections

/console may not work.  Nor do you want to advise that for these purposes.  Terminal Services in Application mode is the most appropriate.

(/console is a function of the RDP client - sometimes it's not available.  And in new versions, it's /admin (and /console won't even work).  Plus, using RDP from a web site, you cannot use either.  And finally, 2008 and later did away with that - it's only available on 2003 - so if you start relying on it, you may get annoyed and disappointed when you change versions.

can someone explain  Terminal Services in Application mode. does it ADD more available connetions? if i buy five does that mean i can now have 7 people on my box? does that mean five per server or five to share on the domain across all servers? do i renew yearly or is it a one time purchase?

Terminal Services has EVOLVED since it was first introduced in Windows NT 4.0, Terminal Server Edition.

There are two general types of terminal services Microsoft offers (the terminology may be a little out of date, but the functions are essentially the same unless otherwise noted).

Remote Administration Mode: Allows multiple ADMINISTRATOR users to connect to the server and MANAGE or ADMINISTER it.  It is not intended for you/your company to install applications and have users run them beyond configuring the applications to be used by others (for example, running an Antivirus configuration/management tool or configuring and monitoring a backup application.  Basically, it's there to make it so you, the administrator, don't have to walk into the server room every time you want to make a change to the server configuration.  Generally, it allows 2 or 3 (depending on version and how it's accessed) simultaneous connections to the server for this purposes.  NO MORE.  

Application Mode: This is intended for use by EVERYONE.  Every user can, POTENTIALLY connect to the server to run a program.  Examples of expected and appropriate use - installation of Microsoft Office and other products (you STILL need appropriate PER USER licenses - one copy of office is NOT SUFFICIENT to allow 10 people to use it on a terminal server).  This can be a cost savings since instead of having to upgrade 10 computers, you only have to upgrade one - LICENSING still costs - but your TIME is reduced since you only have one system to upgrade.  Terminal Services in this mode requires PER USER or PER DEVICE Client Access Licenses (CALs).  Licensing is NOT per CONCURRENT CONNECTION.  This means that if you want 10 people to be able to use the server from their home computers, then you need 10 CALs, EVEN if you only expect 5 to work on it at any one time.  Your "Remote Administration" licenses are not valid for connecting to the server with the purpose of running applications like Office.

FYI: USER CALs are best when you want to assign one user the ability to connect to the terminal server.
DEVICE CALs are best when you want to allow ANYONE to connect but only from a specified device (say a terminal in a factory floor).

Lee W, MVPTechnology and Business Process AdvisorCommented:
Regardless - you NEED to switch your mode and buy licenses.  There is NO LEGAL WAY (and I'm not personally aware of any illegal way) to get more than 3 simultaneous connections without using Application mode and purchasing licenses.  PERIOD.

And you MAY be in violation of licensing by using the system in the way you are right now (I don't know - and I'm not trying to judge - I assume you, like MANY of us, myself included, didn't spend days reading the license agreement - it MAY be that Microsoft limits how you use the software.  I don't know.  But I'm sure you want to be legal in your use of the product, so I'm pointing out the POSSIBILITY).

are there other tools for RDP? like different programs, not web based though like GotoMyPC or webex.

But I prefer UltraVNC or TightVNC... They have a server side component, and a client, as well as a web client. They do not support the MSTSC.EXE, but their own is quick, painless and if deployed right, provide security that is integrated with AD or local groups. It is also easy to remote deploy through scripting to remote computers without actually doing an installation.

You can modify ports to mirror the RDP servers if you wish, although it uses 5900 or 5800 natively (one for web, one for client based.)

Check it out... www.uvnc.com or www.tightvnc.com

Let me clarify after reading your post, that these will not extend your number of clients allowed.
