Right now I have a Citrix Presentation 4.0 Enterprise Edition server farm all of which are 2003 servers. I will be create a new XenAPP 5.0 and have the following question and looking for advice from people who have been down this road already.

I plan on having two Zone so users in both physical office location can connect to their local xenapp farm instead of gong across the WAN also this help with fault tolernace. Each site will have their own license server asd well. how does this sound so far?

-I'm setting up my first xenapp license server and 2008 RDP license server now.

I can only go to xenapp 5.0 becuase some of app are old and 16-bit

I have read that Citrix does not recommend install applicatin directly on the server anymore but is pushing users to use App Steaming? Is this true?

has anyone had luck streaming 16 bit applications that use ntvdm.exe?

What does the XenApp plugin buy for me that I cannot get with the old Program Neighbohood?

Please help and advise

"I have read that Citrix does not recommend install applicatin directly on the server anymore but is pushing users to use App Steaming? Is this true?"

ABSOLUTELY NOT TRUE!  Most apps need to be installed locally on each XenApp server.  Some apps can be streamed but not all.

The old PN is no longer supported.  If you need to use that functionality use the new Quick Launch Tool.

XenApp plug-in is the new technology and is what will be supported and is also required to be installed in order to use the Quick Launch Tool.

An advantage of app streaming is being able to isolate apps from each other.

To isolate on a XenApp server you stream the app to the xenapp server.

Never heard of an isolation zone unless you are talking about application silos.  An application silo is simply one or more XenAPp servers that run a specific app or apps.

Not that I am aware of since Application Isolation Environments have been removed from XenApp.

Just a note, XEN server is used to refer to the XenServer product which is Server Virtualization vs XenApp which is Application Virtualization.

Citrix did not remove siloing, just the Application Isolation Environment.

An application silo is simply a XenApp server that runs a specific application or set of applications.

The old Application Isolation Environment was a special area that was created to hold an isolated application.  It was slow to run and cumbersome to update.  Very few people used it and Citrix and the industry moved to application profiling/streaming/sequencing.

You seem to have experience with Citrix would you recommend trying to stream 16 or 32 bit apps..

Like MS Office Products, Adobe, etc..

Very confused.. I trying to setup a XenAPP farm and have 0 experience doing so

I would recommend installing the apps directly on the server.  ONly stream apps when required as is can be a lot of trouble.

Install the apps on separate servers.  Or, create you a profiler server and learn to profile and stream apps.

Thanks for the help everyone..

BTW, is Feature PAck 3 the latest feature pack out for 5.0 also since I still have 16-bit apps, migrating to XenApp 5.0 is my only choice since 6.0 is 64-bit??

Correct???
