TSGL: Hard times with broken network connections

[Alan Mitchell]

I've seen similar problems which I have been able to resolve by powering
down all network components (PC, router, modem) and then restarting them in
this order. Modem: wait for quiescence on the lights. Router: ditto. MAIN PC
(i.e., the one that you use to manage the router). Once it's connected (and
before connecting any others), verify the status of the connections using
the router's screens. Verify that, if you are using restrictions (number of
PCs or IP range or specific MAC addresses) are all set properly. It probably
wouldn't hurt to do an ipconfig /release and an ipconfig /renew and then
verify that the router is properly assigning your addresses.

Then, still before connecting any other computers, try your browser for an
extended period and see if there are any problems. If not, then power on the
other computers one at a time and see if the "problem" system now exhibits
problems. If so, the most likely cause is the router and, if so, you
probably need to do a factory reset and re-establish all your settings.

Occasionally I have worked on routers that, for some reason or other,
exhibit weird symptoms on direct connect even though the wireless is working
just fine and doing a factory reset has always resolved the problem.

Hope this helps.

Hi,

I'm struggling with continuous network related errors - with my back to the
wall.

Some history:
Unfortunately I can't exactly tell what exactly happened BEFORE this started
about a week ago (but then ... who can?). I've had problems before with OE
not connecting, but this looked pretty erratic. Sometimes some accounts
didn't work, possibly a server timeout. Later I learned that this was
actually 'localhos't, possibly my spamfighting software (spamihilator). 
Removing that program didn't change things, so it looks like these already
were connection problems ...

At the same time I had a lot of BSODs repeatedly - after thorough searches I
changed a memory timing in Bios, which improved things a lot.

My network currently is 1 PC (win2k) + 1 PC (xp pro sp2) on a netgear router
behind a cable modem (cabling) + 1 Notebook (vista) on Wlan from that same
router (works well!).

Now
what I get are broken connections on PC 1 together with repeated event
messages like:

eventsource BROWSER; Event ID 8021: "The browser was unable to retrieve a
list of servers from the browser master "\\ANDREA2400" on the network
"\Device\NetBT_Tcpip_{C70B5AA7-E03A-465C-A1EE-E3EFE858837F}"
    Here Andrea2400 is the second PC on our network, running Win 2k (my
machine is XP pro sp2)

eventsource BROWSER; Event ID 8032: "The browser service has failed to
retrieve the backup list too many times on transport of
<\Device\NetBT_Tcpip_{C70B5AA7-E03A-465C-A1EE-E3EFE858837F}>. The backup
browser is stopping."

I've also seen
eventsource NetBT; Event ID 4321: "The name "ARGEWIEN       :1d" could not 
be registered on the Interface with IP address 192.168.1.3. The machine with
the IP address 192.168.1.2 did not allow the name to be claimed by this
machine.
    Here ARGEWIEN is our workgroup;

I've searched the net for solutions, but didn't find anything that would
exactly fit with what I have ... (also: pretty complicated!)

Sofar I either shut down the network connection and reactivate it, or shut
down internet browser and open it again, or reboot the PC. Only the latter
will give me some tine with a working connection again.

My plans are to (1) get back to an earlier recovery point, about a week ago
(2) delete the network items from control panel and let it install again ...
Any other ideas anybody out there?

Tilman
