My ISP recently changed from Roadrunner to a locally owned and operated
outfit. I had no problems with my home network before, but now one of my
computers will lose some/all internet connectivity after a period of time.
I am on a cable-modem. The problem started when the switchover occur. No
problems for several years prior.
Let's deal with just 2 systems to simplify things:
The problem computer is my Desktop; my Laptop works fine. Both are XP
Home/SP2, similarly maintained, all critical updates installed. They are
hardwired to the same Router (Linksys WRT54G). I even tried switching the
ethernet cables, but this had no effect.
If I reboot the desktop, everything is fine, but after a while, I find that
I can no longer access the internet. Oddly, I can still check email through
Outlook Express. During these times, my cable-modem shows a solid
connection to the ISP. And my laptop has no problem connecting.
Most of the time, if I'm having the problem, I can go to a command prompt,
do an ipconfig /release, followed by ipconfig/renew, I'm again ok for a
while. Oddly, the ipconfig /renew takes from 30-60 seconds, much longer
than I remember it occurring when I've had to do this in the past.
I've examined all the Network and TCP/IP settings between the 2 systems, and
identified 2 differences:
1. Under Advanced TCP/IP settings, "Append parent suffixes of the primary
DNS suffix" was unchecked on the problem Desktop, but was checked on the
Laptop. I then checked the box, and for a while the desktop was ok. Then
the problem recurred (perhaps 15-30 minutes later).
2. When I go to a command prompt, and do a "ipconfig /all" everything is
the same except:
Problem Desktop: WINS Proxy Enabled.....Yes
Functioning Laptop: WINS Proxy Enabled....No
So:
First - is it likely that this accounts for the problem I'm having?
Second - how the heck do I get it "un-enabled" to try? I've been googling
like crazy, found a registry tweak for XP Pro (no corresponding entries in
my XP Home registry), but nothing for XP Home, and nothing in any setting
that seems to control this.
Third - does the slow response to the ipconfig /renew mean anything in
identifying and fixing the problem?
Any suggestions on identifying the source of this problem, and/or changing
the 'WINS Proxy Enabled' setting greatly appreciated.
