Losing Internet Connection Intermitantly

About once a day I lose my internet connection. Doing an 'arp -d *' from
the run line fixes the problem. So it appears that the Address Resolution
Protocol (ARP) cache is somehow getting corrupted? How can I get the
machine so it doesn't keep dropping my internet connection?

Background Information:
-----------------------------------------------------------------
System: Windows XP Pro running Zone Alarm Pro, IIS 5.0, MS SQL Server 2000
(all for development and learning only; this isn't a professional server).

Running the repair option in Control Panel > Network and Internet
Connections > Network Connections > Right Click on Local Area Connection
fixes the problem. According to MS KB article 289256, this option runs
several commands that restore the connection. Here's the article incase
you're interested.

Through simple trial and error I found that the second step was the one
that restored the connection.

Mark, how long ago did this start? I have seen that on Time Warner
too, it started a couple days ago. Are you running IIS or DNS?

At first I thought it was my router, then I took it out of the
loop...same thing...it always seems to between 11am and 2pm EDT for
me...very odd. Not every day but about ever 1-3 days.

Ed,
 
I'm running IIS 5.x but not running a nameserver.

It seemed to start a couple of months ago right around the time I got Zone
Alarm Pro and ran a bunch of tests with grc.com to close down all my ports
and stuff. However, when I disable ZA it still happens. I also tried
disabling MSMessenger and that didn't help though I've been running a
couple of days before it just happened again this morning between 4:30am
and 7:00am pst.

I don't have a router, just the simple cable modem supplied by attbi (now
Comcast). I even plugged it into my UPS to make sure that some sort of
power surge wasn't affecting it and that didn't help.

Other Information: The modem is about 3 years old.

This is a good one that Comcast and ZA support haven't been able to figure
out either.

almost at a resolution.
