That's not his original problem.  He want the feature that controls logins
enabled/disabled to work as advertised.

As far as the Black Hole Effect and the DADE solution.  That particular
solution is a bit dated.  Citrix does have a Hotfix that addresses the "On
Ramp Black Hole".

This is the infamous Citrix "Black Hole Effect";)
This article should help with this problem.

Subject: [THIN] Disabled Logins & Rebooting


 
Here's the situation:
 
I disable logins to one of my servers.  I did this via the CMC and via
the command-line, "change logon /disable", just to be sure.
 
No users on the box.
 
Start, Shutdown, Restart box
 
In the CMC, Load Evaluators, I am seeing the users being directed to
various other boxes.  All of a sudden, 14 users are sent to the box that
was offline and in the process of rebooting.  The box evidently is
marked by Citrix to enabled mode prior to the reboot.
 
This has been a REAL pet PIEVE of mine about when rebooting servers,
that they come backup enabled and ready to accept connections, but I had
not realized the impact it was having as they went down for a reboot.
 
Why is it that a server would be enabled just as it is being rebooted?
and to make matters worse, users are being directed to that box while it
is going down, where the logic?!?!? <RANT>
 
 
So, am I missing something, or has everyone been suffering along on this
issue?
