You mentioned that you had SP1 for ISA, can you tell me where to get it?
Thanks

Subject: [isalist] ISA Web proxy problems when using a published server
http://www.ISAserver.org
Hi, I am new to this list, so apologies if this has been asked before,
but I could not see it in the archives.
ISA server SP1 on Win2k Server Sp2.
1 Exchange server behind ISA using server publishing for SMTP (ex2k sp1,
Win2k Server sp2).
1 Web Server behind ISA using web using reverse proxy. (IIS5 Win2k
Server sp2)
These are three separate machines.
The setup is simple, the ISA has two NIC's one to the ISP, one to the
internal network.
All this is connected to my ISP via a 256kbs leased line.
My problem is this. If I flood the incoming connection with traffic (be
that incoming mail, web surfing, FTP etc) the web connection through the
Web proxy on the ISA will continue to function, all be it slowly, I
hardly ever get a connection timeout. This works well
Now if I have a single large upload to the ISP over the connection
(Large outgoing mail or large file being downloaded from our website,
the web proxy starts to time out on nearly every connection attempt,
when the upload finishes, all returns to normal.
It's as though while, for example, and email is being sent out over the
link, everything else stops, and the bandwidth is no longer divided
between all the clients as it normally is, but given solely to the mail
connection.
I have no bandwidth rules configured.
Has anyone seen this type of problem before, is there away to cure it?
Thanks
Stephen
