This isn't necessarily an ISA question, but this group might be able to help. We have an ISA server with 3 NICs. One to the T1 line, one to our local network, one to the company next door's local network. We have only the default rule for bandwidth allocation in ISA Server. (Nothing else running on this box.) Yesterday I started downloading Visual Studio (1.8 gig). The transfer rate showed that I was getting the full T-1 bandwidth which is what I would have expected. However, other people on our network got very slow response, and the company next door really couldn't access the internet. I was under the impression that under Windows networking if only one person was accessing the network, then he/she would get the full bandwidth. If another person tried to access at the same time, then they would share the bandwidth. (Packets simply being processed in the order they are requested.) Also, yesterday my transfer rate would drop after a while until I paused the download and restarted it. I don't know what that means. We have a Linksys switch on our local network. Can anyone explain to me how this should work? (This morning I am continuing the download and I seem to be getting about 300-500kb/s on average. But since everyone else has access I'm reluctant to change anything. It would be nice to get the full bandwidth though.) Thanks. Guinn Guinn Unger Unger Technologies, Inc.
