Ok, you are not going through the CSG based on this:
Address=servername.company
1494 is not used for CSG, everything goes through 443. The screen shot tells us the issue at hand though. Edit your STA entries to reflect port 8080:
http://servername2.company
Your entry will use port 80 (http's default port, get it?)
First, make sure that your test machine has its Root Certificates updated. I see tons of people run Express on their Windows Updates and never get their roots updated. Now open your mmc, add the certificates snapin and look around the trusted certification authorities for a cert that matches yours. I use GoDaddy for example (they are cheap and local); here and there I find users who don't have the Intermediate cert we go through but, for the most part, it works without intervention. That is the whole point of buying certificates.
Now I did a search for DoD certificates and I immediately found a site telling you how to install the certificates on client machines. Sounds like they are not preloaded on common operating systems or pushed via Root Certificate updates.
https://acc.dau.mil/ifc/do
BLIpman,
I think we are almost there... :)
I have one user manually installed the latest DoD certs and have him test with IE7 and IE8 settings.
I have about 5 ctx server desktops published for the user, right now he say that the connections to the server desktops vary. Sometimes he can connect and sometimes he gets "The Citrix SSL server you have selected is not accepting connections." Again, it is random...
He will update me on Monday with his testing results.
Thanks,
Ok, do you have 5 separate desktops published and each goes to one different server but the problem is random or do you have one desktop published to 5 servers, it load balances, and the problem appears to be random? For testing individual servers I like to publish something like notepad and will label them Notepad on Server 1, Notepad on Server 2, etc. This is handy for checking servers individually and for testing printing while you are at it.
Yep, then let me know which ones you are having issues with and we can work them out from there. Connection issues will often present themselves in the event viewer of the application server and or the web interface/secure gateway server so post anything you see that might be interesting. Also, compare working launch.ica files to those from servers that are not working.

An error occurred while attempting to connect to the server CTX3 on port 8080. Verify that the Citrix XML Service is running and is using the correct port. If the XML Service is configured to share ports with IIS, verify that IIS is running. This message was reported from the XML Service at address http://CTX3:8080/scripts/w

5. Site path: c:\inetpub\wwwroot\Citrix\
The Citrix servers reported that they are too busy to provide access to the selected published resource. This message was reported from the XML Service at address http://CTX4:8080 [com.citrix.xml.NFuseProto
This might be useful for the first error but let's try to clear the others up first, I am not convinced you have a corrupted application:
http://support.citrix.com/
Verify that all servers running your published applications are using 8080 for XML (you can check the properties of each in the AMC to verify this). Then, assuming you are on the right port and didn't accidentally set 80/share with IIS on one of them, reset the XML service, make sure it comes up without generating new events, try that server again.
Verified that all CTX servers are using 8080 for XML port. Still waiting on external user's test outputs.
Meanwhile, I have published notepad from each server such as notepad_CTX1, notepad_CTX2, and so on, and I still get "Cannot connect to the Citrix XenApp server. The Citrix SSL server you have selected is not accepting connections." randomly. However, if I try a few more times I finally get connected. User load should be less than 3. Any ideas? Thanks.
I am sorry, got tied up with some issues at work. I am glad you are using a load balancer because it makes the issue much easier to solve. You need to enable sticky sessions (or whatever your load balancer calls "persistence"). If you start a session with one server and then the load balancer takes you to another the session ID won't be recognized and the new server will drop the connection. Then, finally, the LB takes you back and the original server can work. It explains your issue pretty neatly.
Let me get one thing cleared up first, do you have more than one Web Interface or CSG server? If not, then is the load balancer in the back end trying to balance connections to the Citrix farm?
Citrix does it's own load balancing to farm servers and will do a better job than any hardware LB you will put in place; it has all sorts of server metrics it can use to better distribute load. To load balance Web Interface or CSG servers you must guarantee that a "flow" (a user's session or a combination of a unique IP/port combination) always goes to the same server it started on.
Load balancers can usually sticky on things like:
-source IP
-SSL session ID
-URL cookie
-file based cookie
etc...
Thanks for coming back :) :)
Here is little change took place in the past 48 hrs.
Due to the DoD Cert mismatch I had to move the WI/SG in the trusted network. (10.x.x.x) from DMZ, and it is operational.
I only have one WI/SG for now. Eventually will have one more.
LB sits in the DMZ and it is just forwarding ips from external to internal (sort of NATing, it is not LBing) and not balancing connections to the CTX farm. Hope this answers your question.
My question is if I still experience this behavior below what would you suggest?
["Cannot connect to the Citrix XenApp server. The Citrix SSL server you have selected is not accepting connections." randomly. However, if I try a few more times I finally get connected.]
Thank you,
So on the LB device, you have a Virtual IP which defines some sort of "service" and that forwards traffic in to your WI server right? You only have one real server defined thus far though so it shouldn't be trying to go anywhere else. I am not sure this is the issue but it is a suspect. When you say you try and try and eventually it works I start thinking about the IP layer and what might be going on there.
Are you still getting errors on the WI/CSG or on the individual Citrix servers? Another thing to try is taking out all but one of the STA entries to make sure you are not hitting a bad one (or somehow misconfigured) but you should see event log entries for any STA failures.
Based on the info you provided;
Your using the SG therefore you only need to have port 443 open on your firewall to access this. This allows outside clients to communicate to the SG, the rest of the communication e.g. 1494, 2598, 8080 happens inside the network and shouldn’t need to be open to the outside.
The other problem I see is your running XML on port 8080, which is fine but you have your STA links listening on port 80 (hence the http:// only) try changing your STA links to:
http://servername2.company
http://servername3.company
This should resolve your issue(s)

Do they get the same error from the LAN as from outside the network? Would you post the contents of a launch.ica file so we can see what you are getting out of the WI?
