I have ISA Server 2004 behind a router with 2 MB ADSL connection and about 30 users using work group.
some users use download managers that consume all the bandwidth and others get no connection at all.
the problem is :
1- I need to distribute the avaliable bandwidth equally to the online users ( i mean that I don't want the speed to be limited to 15k/sec or else ... I need all the users downloading at a time to have the same speed in a fair distribution.
2- I would like to know how to block an application Like ( Internet Download Manager IDman.exe )

Thank You

1. Without getting a 3rd party add-in, you cannot balance/alloacate the traffic through ISA as ISA does not care about the bandwidth.

2. to block the program, if you are the admin, then remove their programs.

3. if you want to block their activity then first you need to be able to identify the traffic.
You say you are on ISA2004 so you need the added elements supplied with SP3 if you haven't already installed it.

If necessary, install the downloader on your own PC so you can generate the traffic to monitor.
Open the ISA gui - select monitoring - logging - click start query to start the realtime log
Watch the traffic that is going through - can you oidentify the sites that are being visited to get the downloads from?

On your PC...
Make a connection from the client and try and do a download using the program
Watch the traffic go out then click on the line in the log. In the bottom section you the drill down and identify the http headers and see if their is a common user agent associated with it.. You may need to check a number of the linhes and drill down. Once you have the user agent name for the program your laughing. You can then add a rule and use the configure http option (for that rule) to block the user agent name.

Job done - repeat for each occurrence.

That is a different question and needs to be posted as such for the installation of a 3rd party product.
Be aware though that Surfcontrol has been purchased by websense and some of the surfcontrol products are being discontinued from January.

Read the websense and GFI Monitor reviews and see what best fits your requiemnents.
