[THIN] Re: Desktop sessions trying to connect to unpublished desktop

Hi Bob, 
 
Where is the best place to start researching the ICA protocol and related 
technologies:  
 
e.g.  
 
? Secure ICA Client deployments 
? How to avoid ICA client connectivity issues 
? How to debug ICA Client errors 
? How to monitor and tune ICA Client Performance 
? How to not be a geek :-)

Jo, 
  
Are you sure this wasn't a master browser problem? 
  
In our environment, we have our master browsers aliased in DNS to something 
like mb1.domain.com, mb2.domain.com etc. 
  
If we are doing maintenance on a browser, we'll redirect clients to a 
browser merely by updating the alias.  Recently I forgot to do this, and 
when a server came up in a problematic state, clients were trying to connect 
to it for published application resolution and getting messages similar to 
the ones you posted below.

Subject: [THIN] Desktop sessions trying to connect to unpublished desktop  
 
 
 
 
We have a citrix farm, with a published desktop. We have approx. 70 servers 
that desktop is published from. At the weekend, we unpublished all but 5 
servers, so that maintenence could be carried out on the rest of the farm.  
 
Later we started to find that people were having issues connecting to the 
published desktop. People were either  
 
"There is no Citrix Server configured on the specified address"  
"The citrix server you have selected is not accepting connections"  
or  
the connection hung at the connecting screen.  
 
The issue was that as the clients were connecting, they were connecting to 
the Master Browser normally, but were then some connections (but not all) 
were being allocated to the server that wasn't published, and was in an 
unusable state(server wouldn't accept RDP or ICA connections). Rebooting the 
server resolved the issue, and connections were then handled normally.  
 
I would like to understand why we had this issue, and would appreciate ideas 
on the best route of investigation.
