I'm running IIS 4 and an SMTP server (post.office) on separate
machines (each running NT-4 server).

On the local LAN, accessing the WWW site (and downloading large files
from the site) is relatively fast, and so is POP-3 to the SMTP server.

However, when accessing the WWW site or pulling e-mail off the server
via the internet connection (ISDN) and while monitoring the bandwidth
usage on the ISDN router, it's clear that some sort of throttling is
happening (ie continuous utilization of 100% bandwidth is not
happening for both large WWW file downloads nor pop-3 email access
with large attached files).

In the IIS control panel, there is a bandwidth setting where I can set
the max bytes/second that IIS will serve up. It says that setting
will supercede some global maching bandwidth or throttling setting.

But it doesn't say _where_ that global setting is located.

So, is there such a global bandwidth setting for NT-4 server, and if
so where is it?

PS:

Is there a newsgroup called

microsoft.public.inetserver.iis.smtp_nntp ?
