Can open published desktop or applications on new XenApp 6.5 farm

I have just created a new XenApp 6.5 farm for testing purposes.

I have deployed:
*  Web interface server (v5.4.0.95) - Server 2008 R2 SP1
*  Primary Data Collector - Server 2008 R2 SP1
*  First Xenapp 6.5 server - Server 2008 R2 SP1 (where apps and desktops are publsihed from).

Database running on SQl 2008 R2.

I remember I had this issue when I rolled out my first XA6 farm about 2 years ago. It had me beat for months!

When trying to open either a published App or Desktop via either the web console or receiver (we will use the web console in this case), we see the following error:

 CWI Error
I check the event viewer on the WI server and see the following error:


Site path: C:\inetpub\wwwroot\Citrix\XenApp.

The Citrix servers reported that they are too busy to provide access to the selected resource. This message was reported from the XML Service at address http://MyDataCollectorServer:8080/scripts/wpnbr.dll [com.citrix.xml.NFuseProtocol.RequestAddress].  [Unique Log ID: dd734987]

For specific information about this message, see the Web Interface documentation at http://support.citrix.com/proddocs/topic/web-interface-impington/wi-log-messages-event-ids-hardwick.html.


I check the Data Collector servers event log and see the following msg:

A usable server cannot be found on which to launch the application. Application: Test XA65 Published Desktop, Client: WI_9b9A1cSqiB6Mzhpw7 (address: Clients IP Address;;;), User s Username. Check your worker group definitions and load balancing policies to verify appropriate servers are assigned for Test XA65 Published Desktop.

No load balancing policies are in place apart from the default one. Load seems fine. There are no event log errors on the Published Desktop/App server.

If I go back to this similar issue 2 years ago in XA6, the resolution was to make sure Windows 2008 R2 Service pack 1 was installed, XA rollup packages and hotfixes were installed and it all worked. However I have replicated this in the new XA65 farm with no luck.

The only thing I can think of is that the issue is to do with the WI server.
My XA65 farm servers are running on port 8080 for XML. So I have replicated this on the WI console. See attached image:

I am not using a CSG for this test farm, so have kept the WI with all of the default settings. See attached image of access type:

http://MyDataCollectorServer:8080/scripts/wpnbr.dll

So you have setup your "MyDataCollectorServer" to be the XML broker - then ensure it is listed in the configuration.

However are you sure your XML is listening on 8080? To ensure this is so run the following on your XML server:

1. Stop the Citrix XML service
2. Open elevated command prompt
3. Type ctxxmlss /u to unload the Citrix XML Service from memory.
4..Type ctxxmlss /r8080. This forces the Citrix XML Service to use TCP/IP port 8080.
5. Restart the Citrix XML service

Did you change the Citrix policy tor the XML port, it will default to 80 but you can set it to 8080 using the computer configuration Citrix policy.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

I have changed to port 80 on both the WI server and the XA servers (removed the XA servers from the farm and re-added again with port 80).

Same result.

This is the error I had with XA6 a few years back. Looks quit similar to what you are experincing. Althoug it says PS4 it also was applicable to XA6 and I assume also to XA65.

"To allow connections through Web Interface 5.2/5.3 to a Presentation Server 4.0 farm, the following parameter must be set under the webinterface.conf file":

RequireLaunchReference=Off

can you try taking the server out of the worker group and add it for the published application as just the servername?

Last 2 comments unfortuantely did not help. Thanks anyways.

I just ran a qfarm /load and both the test servers show a load of 20000.
Not sure why? There is no one connected to them and no one ever has.

How can I reset this load count?

Is it possible it is my license server? I have read a few articles which refered to this.

The current licenses are for XA5. I am waiting on our reseller to sort out the renewal of our Citrix subcription so I can redownload the license file to work with XA65. However I was under the impression i would still be able to use the XA65 farm for testing purposes.

Ayman BakrSenior ConsultantCommented:
Yes it is most probably a licensing issue.

And yes you can use the XA 6.5 for testing purposes with an evaluation version; however you still need to install the evaluation .lic file I believe.

Tony JLead Technical ArchitectCommented:
Mutawadi is correct - you need to request temporary/eval licenses as XA doesn't include any by default (which if you think of it, it can't, as they're based on and tied to the host name of your license server) - XA 5 cannot license XA 6.5 (although the opposite will work - 6.5 can dish out 5 licenses)

HowzattAuthor Commented:
Thanks for that.

We currently have a XA5 farm in production. i am using the XA5 farm license server for the new XA65 farm. If I import eval licenses, will this impact the current license in use with the XA5 farm?

MeultjeCommented:
Isn't it possible to install the licenseservice for the new farm on a different server. Than you can build a new farm beside the existing XA5 farm without any issues. The only thing for the new farm is to point to the new licensing server..?

Tony JLead Technical ArchitectCommented:
Yeah you really need a new license server to dedicate to your test environment otherwise live users will get test licenses AND you would have to pay for updated ones because you would have to have upgraded the license server components which won't allow the use of XA5 licenses...

1)Try local intranet access and self-citrix server first , everything fine then
2) trouble should on your routerfirewall, port release NAT.
