Alternatives to Citrix Remote Computing?

Dysfnctnl85 asks: "The company I work for relies heavily on remote computing through a Citrix MetaFrame server. The reliance on this stems from the structure of our accounting software and the fact that we have 2 remote sites that need to access this data all day, everyday. We are investigating alternatives to the Citrix system we currently operate. How do companies of similar structures deal with this type of problem? Is it feasible (or practical) to use Windows Terminal Services to achieve everything Citrix is capable of doing? This includes, but is not limited to, the ability to print from the Citrix session to a user's printer, the ability to access network drives from the Citrix session, access the user's local drives through the session, and the ability to use published apps. The main concern with this type of setup is the ability to print. What alternatives are there to Citrix?"

MSTS

Seeing as I use MS Terminal Services to do everything you mentioned, I'd say you could fairly easily kiss Citrix (and it's relatively large licensing fees) goodbye. I've migrated 99% of my company to Thin Clients RDPing to MSTS2003 servers, and could not be happier. Four branches nationwide, and (excepting servers, of course) less than 5 non-thin-client systems, 2 of which are mine. It is salient that MS and Citrix have cross-licensing and other business-partnership-type agreements, which I believe include code sharing. MetaFrame is built on top of TS.

WTS is good enough

I work in a company which does mainly Application Server Providing, and we switched about 2 years ago from Citrix MetaFrame (1.8) to Windows 2003.

Printing works well enough, you just have to install all the necessary drivers on the server and make sure the clients use the same drivers (though universal printing engines like ThinPrint and others will work too).

Local drives work like a charm (although only since 2003), you can even copy files with Ctrl+C and then paste it in your local explorer with Ctrl+V (I don't know if the newest Citrix also supports this). Network drives work as expected.

We don't use published applications, and as far as I know Windows doesn't support this. You *can* specify an application to run in the client, but I never used it.

Our customers all connect over the internet, and the performance is pretty much the same as with Citrix. We did some tests with Presentation Server 4.0, and it performs a little better with images because it has a better caching mechanism, but the difference wasn't enough to warrant the (much) bigger licensing costs.

I also tested the NX server from NoMachine, which supports proxying RDP sessions. The site claimed speedups from 2-10 times, although in my experience it was between 1 to 2 times, and because printer and drive redirection needed additional setup, we didn't continue with this. But for X11 sessions NX is currently the best thing (IMHO better than UNIX Citrix).

So, if you only need to provide Windows applications, WTS is a good enough replacement for Citrix. There's also an official client for OS X and an Open Source client for UNIX (which supports RDP 5.1 as well as printer and drive redirection).

RDP stems FROM Citrix and the ICA protocol. Citrix was suckered into sharing technology with Microsoft so they could get direct access to the underlying API's a few years back. Citrix was smart in that they didn't share the ICA protocol with MS. MS then developed RDP as their thin protocol. Problem with that is that RDP has a 25k footprint where ICA can cruze just fine on 14k or even less. I guess if you have fewer users and don't care about bandwidth and server costs, then MS Terminal Services are for you... /rolls eyes....

For your Total Cost of ownership... Citrix is the way to go... I can't tell you how nice it is to publish an Application and not the entire desktop. That saves you from dealing with users who delete things or generally like to tinker. Add automatic printer creation and it's a no brainer.

MS did what they always do... they stole the technology and branded it as their own. Remeber in the beginning of Citrix (on NT 3.51 and Winframe 1.6), you didn't need MS terminal services at all... in fact it didn't exist!!!

There is also a product by 2X Software called Application Server which handles the Published Applications side of things as well as the Load Balancing of Terminal Servers.

However they are still working on integrating the two, this should be added in the near future. The products target directly Citrix customer's base and are slowly implementing almost all if not totally all Citrix features and more at 1/10th of the cost.
