The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Could not find the specified XenApp server Error

Asked by DanaWilliams in Citrix

Tags: Citrix

Everything was working fine, and then one day users could not connect. When anyone would launch any published application they get the error, "Cannot connect to the Citrix XenApp server. Could not find the specified XenApp server."

Heres our setup. One Citrix XenApp server 4.5 on our Windows Domain and in the production network. One Web Interface server 4.5 on our Windows Domain and in the DMZ. One Secure Gateway server 3.1 in a Workgroup and in the DMZ. All three servers have server certificates installed. The WI and SG are on the same subnet and the same switch, as well as our Bluecoat proxy server, if that has anything to do with the process. The XML service is on port 8080, and session reliability is enabled.
 
There were no patches applied, GPO changes, or modifications to any of the Citrix servers around the time the problem started. The network guy does not see any drops or rejects from WI & SG servers to the PS. In fact he does not see any traffic at all going to the PS from those two servers. On the WI, if you change it from Gateway Direct to Direct, users can connect just fine. If you try from the WI, telnet securegatewayserverIP 8080, or from the SG, telnet webinterfaceserverIP 8080, you will see a connection failed. I have tried turning off session reliability, but that didnt make a difference. You can ping both the friendly name and FQDN from every server to every other server.
 
I have built the WI from scratch twice, and the SG from scratch once, but I still have the same problem. I have tried WI 4.6 & 5.1.1, but the results are the same.

I couldnt figure this out Friday night, all day Saturday, and Sunday, so it time too ask the experts. Help!
 
Thanks,
Keith.
