Slow Download speed.

The Scene:
I have a customers Server with SBS2000 installed, using ISA 2000 with 2 Network Cards. We recently changed the ISP (upgrading 512Kb to 8Mb line) keeping all the same hardware, and had a sudden drop in speeds (stuggling to get over 30kb/sec download). I have checked all latest SPs are installed and they are. I have checked the sites i am downloading from (i am using SP2 for XP for a file test) and they work fine.

The Problem
If I use Firefox of IE to download this file i only get 15-45Kb/s but if i use a program called "Free download Manager" i get 200+Kb/s either thru the Proxy or direct to the internet and with Realtime monitoring of the CA AV on or off.

Any Ideas? im completly stuck, thanks in advance.

after some checking, it seems Free download manager does 4 connections, so uses 4 of the "connections" thru the ISA server, so it seems that its some limit on the ISA server, how can i change this? as it seems "stuck" at 45Kb/s atm and i cant make it go any faster.

Have you checked if a third-party tool like Bandwidth Splitter is installed on the server?
This could cause your problem.

Well, we managed to sort it out, seems the issue was we needed to change the exteranal NIC to 10Mb not 100Mb and now the connection is flying at a nice 700MB/s.
