[THIN] Re: Terminal Services stops responding to new connections

Yes, we had a similar situation in which a customer was using an older
imaging tool.  The print monitor for that program did not play well with the
Citrix Printing Service.  As a result, the sessions would end up in a down
state and the problem you've described would ensue.

 

Sorry,  no resolution.  The customer learned to live with the problem as
they are migrating to a new imaging tool and did not want to spend anymore
money fixing the issue.

 

If it's network related,  you could try disabling Receive Side Scaling and
Task Offloads as they are known to cause the same/and other issue(s).

Subject: [THIN] Terminal Services stops responding to new connections

 

Hi all,

 

Hopefully someone on here will be able to help.

 

DL360G4p servers running Windows 2003 SP2 / Citrix PS4 R04 

 

We have a problem with our PS4 servers stopping responding to new rdp or ica
connections.  Also, if you try and logon at the console it lets you enter
your username and password then just sits there on a blank screen and never
logs in.  Users on the server at the time work fine but no new users can
connect.

 

The only thing we can do is wait until all the users are off the server and
physically power cycle the server.   Then, it will last a few more days and
it will happen again.

 

Has anyone seen anything like this before?

 

The only thing I've found so far is the following error in the event log:
