have about 70 Citrix Servers in my farm with users running Citrix Published Desktops. WE have had no issues with CPU on any of our internal applications. The problem is that we have people who like to surf the we on a lot of the PC's that our out on the Generic Login thin clients. I plan to later do published apps and move IE to its own server, but user's internet explorer sessions are always hanging up. Now this is 2 or 3 out of maybe 1500 sessions per day, but its still more than I would want to deal with. On a daiily basis, I have to go out and kill an iexplorer.exe CPU process for a user because it is sitting at 25% to 50%. I know I can use CPU Utilization Management to set slices, but Im trying to figure out why IE keeps doing this. Is it something related to Citrix, is my Symantec causing issues (version 10). Its becoming very frustrating. Im on Presentation Server 4.5 Rollup 4.
