citrix xenapp and revit 2012

[dmorin]

we have a computer setup to run citrix and revit. Computer specs are

Dual xeon X5670 2.93ghz
48gb ram
1gb nics
2 500gb SAS – raid
1 360gb OCZ ibis solid state drive with HSDL link
nvidia quadro 4000

xenserver 6.5 free install with 2 virtual servers running 2008r2(one has xenapp 6.5 and the other citrix lic manager.
We have installed office 2007, sketchup 8, speclink+, bluebeam, costworks, abobe CS5 and they all work fine. Got autodesk citrix network license. Install network license manager on the xenapp server along with revit 2012. Open revit on the server and it opens fine and gets a license. Login with citrix receiver and the user doesn't get a license when revit is open and the program will not open. Login citrix receiver as administrator(same user who everything was install under) and it will get a license and work fine. Anyone have any idea why other users can't get a license? Also any ideas on how to get hardware acceleration enabled in revit and sketchup. Can't get them to recognize the video card

Just in case anyone else runs into this issue with citrix or even just NLM for autodesk products on a 2008r2 server. This issue ended up being the version of NLM we had installed. Our office is a IPv4 network with 2003 servers and win 7 machines. The citrix server is a 2008r2 server and this is where the NLM for our citrix products is. We had installed the network license manager for IPv4 and disable IPv6 on the 2008r2 server since we are a IPv4 network. Taking the 4 EXE files from the NLM IPv6 version and overwriting the IPv4 EXE files then NLM started handing out Licensees to everyone. Autodesk said even if you do not use IPv6 for some reason NLM still must use some protocol when installed on a 2008r2 server.
All is good now, we have hardware acceleration enabled on revit and autocad architecture 2012 versions and they are performing VERY well over the WAN. xenserver 6.0(allows GPU passthrough to VM server with xenapp 6.5) with xenapp 6.5. We are still trying to decide about publishing the apps from xenapp to xendesktop or just leave it how it is setup now. So far we are very pleased with performance compared to hyper-v, remote desktop RDP or even riverbed steelhead that we have tested over the WAN!
