how to replace desktops with think client and terminal server

We're in the phase where we may decide to replace all of our desktop pcs with thin clients and terminal server. But I'm a bit hesitating because desktop pc with oem windows license is so cheap. I need to do research what setup is needed for server and hardware and license cost. If you have done similar project, can you share?


Environment will be as following;

20 clients, 7 of them need microsoft office. rest need just widnows and will take reservation (custom software loaded). Windows 7 needed.

I guess I need one terminal license for each concurrent client accesses and windows 7 license?

My company has started rolling out HP thin clients, but not at this location yet.

I have had some training.

The problem we would have is to my understanding Custom Programs cannot be run on a thin client, I may be proven wrong.
That said, not sure what you meant by:  (custom software loaded) that may cause an issue for you.
HP's thin client computers come with Windows 7, but may not have full functionality.
I will be watching what others have to say.

crcsupport,

...will take reservation (custom software loaded)

Do you know if this custom software is terminal server compatible?

FWIW: I have several clients, include my own office,  that have 20-25 users all running off a single 2008 R2 Terminal server with a SBS 2011 server on the back side. All user apps are  installed and run frpm the Terminal server. There is no software installed on the clients execpt a RDP client. They use Thin clients, PCs and  Laptops (old and new), Kindles, iPads, Android Table3ts, and/or any device that has a RDP client app.

Some of the great things  about thin clients:
1)  nothing can be installed on it bu the user. No viruses, spyware, etc.
2) Since everything is on the terminal server, if a Thin client has issues or fails for any reason then you can just swap it out.  No software or data to transfer from the old thin client.

With thin clients there is very little support required.

20 clients is not many, to consider when thinking about the rollout of Terminal Services, versus the cost of new PCs. Don't get me wrong been rolling out Thin Client Technologies since 1993, larger the rollouts the larger the cost reduction.

Also remember if a server fails, all eggs in a single basket, no-one can work, unless you build in resilience, and have at least two servers, and then you will need to use roaming profiles to central storage NAS or File Server, to ensure profiles are roaming between Terminal Servers, and then you may want to use File Server for storage of home drives and group shares.


This EE Article talks about re-purposing PCs for use with VMware View (VDI), but the same could be done with PCs for RDP access.

there's another book here by fellow vExpert Mike Laverick and Barry Coombs also about re-purposing PCs

PC's can also be locked down with Group Policies to provide a locked environment.

Yep, the custom software is terminal service safe. I tested with 5 default RDPs, seem working fine. I checked the price of thin client, ranges to $300 well, I would just forget and buy Dell PC from ebay, it seems really not suitable to our environment.

Thank you guys
