We are running a 2 server citrix farm using E2K3 and are serving out desktop sessions to 80 users.
The main issue that we have is that the Iexplore.exe processes in the task manager are using huge amounts of memory.

The usage is between 256,000k and 140,000k. there are 8 sessions in this range

My question is, how can i set limits on applications / processes in citrix and what is the effect on the user

I have increased the points on this question as I am quite new to the EE and not sure of the right level to match this question.

If i could be pointed in the right direction then I will do some more research on the question my self.

Is it the same users that are using all of the memory?  Do the users use IE as part of their sessions?  I try to lock down my IE, but sometimes you can't if your users need it.  If you find it is the same users that are using the memory check to be sure they haven't downloaded some toolbar like starware or whatever in their profile.

What version of IE do you have?  Are you using UPHClean?

Thank you for the comments,

We are using IE6 at the moment. I will check the sessions and users as suggested.
I have not tried UHPclean,
is this a utility that should be executed frequently as a housekeeping task or only when we have events as desribed in the MS article?
"event ids 1517 and 1524 "

apoligies, I didn't answer all of your questions.

 Do the users use IE as part of their sessions?  Yes they do as the local Host pc's / terminals do not have internet access  and we havent published it as an application.

Well, UPH clean will help if your users are getting sessions with iexplore that is hanging.  

But some is going to depend on what your users are allowed to access inside of their citrix session.  For example, right now just accessing this site is using about 32,000 kwhile I am inside a citrix session. If your users are watching videos or streaming music then it can go up dramitically.

UPH clean runs on your server and terminates session that log off.  It is helpful if things are still trying to run after the user logs off.

Is it the same users using up all of the memory?  Use task manager and see if it is just one or two users using it all up or if it is evenly distributed.  I would think chances are you have one or two users taking advantage of the internet connection and doing things they aren't supposed to.

Thank you for the advice, I did find a lot of toolbars and other rubbish which I have removed ,which has helped the systems. I didn't run UHP clean yet as on reflection we have decided that 2 servers are not enough for the ammount of users we have, so we have decided to builda new farm using Xen on 2 new servers and will then rebuild the old servers and add them to the new farm.. Thanks for your help and advice
