Hi,

We are having a problem with one of our Terminal servers. It is a windows 2k
TS. It has dual Xeon 2.4Ghz cpu's and had 2Gb of RAM installed. We have 50
users connected via T/S.

What is happening is that the server slows down to an unacceptable level
during the day and we need to reboot to get things running smoothly again.
The cpu usage is between 30 and 50% most of the time. We were told to add
more RAM so we increased the memory to 4Gb. However Windows only reports as
seeing 3Gb RAM, and it has made no difference to the performance.

Does any one have any suggestions?

Would Citrix perform better?

Many thanks

Derek

PAE = Physical Address Extension

The use of the /PAE flag in boot.ini is explained in the KB article
below. Problem is that the /PAE flag should not be needed to access
memory up to 4 GB, only above 4 GB.

Windows 2000 Utilities Do Not Display Physical Memory Above 4 GB

I would suggest that you use Performance Monitor to find out what is
causing the performance problem. If you have an application that
constantly leaks memory, adding RAM is not going to help you.

Since Citrix runs on top of Windows Terminal Services, adding Citrix
is not going to help you either.

Have had some success with a product called appsense. This releases memory
and also protects CPU from heavy users taking all the CPU leaving nothing
for the rest.

I got mine from a reseller www.thinstore.net and a 30 day trial is
available.

Good luck.
