Xenapp 6 and MS Windows 2008 R2 SP1 - Known Issues.

Symptoms :   Although Citrix Systems supports Microsoft Windows Server 2008 R2 SP1 with Citrix XenApp 6, users of Microsoft Server 2008 R2 SP1 must be aware of certain issues when using it in conjunction with this product as outlined in CTX122601 - Microsoft Windows Server 2008 R2 - Known Issues
You cannot connect to Citrix sessions when Microsoft Windows Server 2008 R2 SP1 is present.
Trying to use the quick launch tool CTX122536 – Citrix Quick Launch to the server IP address hung at: “Connection established. Negotiating capabilities...”
“Qwinsta” from a command line returned no information and just left a blinking cursor.
Svchost.exe crashes in TermService









Trying to use the quick launch tool to launch a published application hangs at “launching.”



Note: When verifying this issue against the release to manufacturing of Microsoft Windows Server 2008 R2 SP1, the reviewer was unable to install the Citrix Hotfix XA600W2K8R2X64001 on this unstable server. The windows installer seems to hang, but upon restarting the server, the hotfix is installed.

Workaround :   Install Citrix Hotfix XA600W2K8R2X64026, CTX127360

Citrix XenApp 6 – Why it doesn’t spread ?

Citrix XenApp 6 is one year old product already and still not wide deployed (In my country at least, France). Why ? I think about two reasons :
Mostly because you can install XenApp 6 only on Microsoft Windows 2008 R2 which is only 64Bits operation system from Microsoft and because there are many features just disappearing from this version but a lot of new ones.


XenApp 6 :

• No more Installation Manager (Just remain a read only console to deploy past packages)
• No more Resource Manager (EdgeSight is suppose to do the job)
• No more Access database for the DataStore, now it’s replace by MS SQL Express 2008
• No possibilities to have mixed farms
• Farms settings are now store in IMA and/or Global policies
• New feature, Worker Groups
• New feature, Global Policy (XenApp Policies in the Active Directory)
• New management console (Only one !) Citrix Delivery Services Console, at last
• Simplified Install
• HDX RealTime Collaboration & HDX RealTime audio

Can't run RSOP.MSC ........ Access Denied.

I was trying to track down an issue today that I thought was group policy related. I kept getting access denid when I tried to run the RSOP.MSC. I found an article on the web with the fix.

cd %windir%\system32
regsvr32 /n /I userenv.dll
