Logging Loss of Carrier for a Persistent Modem Connection

[Peter Court]

I'm using NT 4.0 SP3 with Routing and RAS and RAS Hotfix.
We have a persistent modem connection (i.e. permanent)
with a fixed IP to our ISP (Telstra).

We are having problems with loss carrier. It appears
that when external users surf the WebSite OR the Post.Office
Admin Web Server from outside, often after 10-30secs the
line is dropped. Internal users can surf out for hours
(via MS Proxy 2.0) and Email works fine in both directions.

My questions are:
1. Can anyone explain the how external users surfing the site
or the Post.Office Admin Web Server could cause the line to
hang up ?

2. How can I get these lost connections to be logged in the event
log ?

Normally the link redials and establishes itself OK, but many
redials dont work, and in all its not ultra reliable. A related
problem weve had is that the DNS server fails after the link
drops (or indeed after a boot) and has to be restarted after
the link is up. For now we are reverting to a hosted DNS soln,
but I'd like to solve that if poss too.

If you enabled Modem Device Logging you get entries for each
hangup event in the Modem (ModemName).txt. This is enabled by
Ctrl Panel, modems, Connection, Advanced, Tick "Record a Log File"
The file is in the Winnt dir called Modem (ModemName).txt
(eg: ModemLog_Banksia MyFastModem 336.txt).

I'm still totally perplexed whats causing my modem to drop when I
surf to the site. We've completely re-installed, and even removed
RRAS, and Proxy.
