[THIN] Re: Major bandwidth issue XenApp 5.0

Are you using any third-party printing products?  The CTXSCRD was the OEM VC at one time so there may be some other implementations that use this channel.

Subject: [THIN] Major bandwidth issue XenApp 5.0

 

ICA sessions connected to XenApp 5.0 are using continuously a lot of bandwidth on the CTXSCRD

virtual channel , despite the fact that we have turned off all options we know off which uses this

channel (for example SmartCard).

 

And because of this issue, ICA bandwidth usage has DOUBLED (!) since the switch to the XenApp 5.0.

Previous farm at this customer site was Citrix MetaFrame XP.

 

When we minimize the bandwidth on this channel with smcconsole, bandwidth DROPS significantly.

But we have to do this manually for each session (customer has more then 600 remote ICA sessions).

 

 

I have 2 questions:

 

- Has anyone seen this issue ?

  Which Citrix policy settings could maybe cause this bandwidth issue ?

 

- How can you turn of automatically, on server level, the same we now do with the smcconsole.

 

 

Any suggestion would be very much appreciated !!

 

Thanks.
