XP-Pro UNC network locks up several times a day, what to do?

Bo Berglund

I will use all of the hints below to see if anything works out.
But tomorrow is the last day at the office for almost 3 weeks so I
might not get it all done.

Thanks for your valued help!

With WiFi network (lines may wrap). My PC is named WVBYBOBEL:

C:\Program Files\Support Tools>browstat status

Then I disconnected WiFi and connected wired network:

This produces the following output:

Looks like it is not this issue either....
My best bet now seems to be to go wireless for good. The wired network
connection is 10% blackouts now....

You're right. This doesn't seem to be the problem. But it does point
out another issue. It appears you have 2 transports bound to the
browser for the same domain (SYSTEM3R). It might be that only one of
these is actually connected in an operational sense (probably #1) and
if it picks the wrong binding, you may be waiting for a long timeout
before trying the other binding. When working wireless or over VPN,
you may only have one active binding -- eliminating your problem.

To test this, try un-binding one of the connections. The following
command will unbind connection #2 above, leaving only connection #1:

browstat unbind 2

Then test it with only one binding. This "unbinding" is temporary and
will hold until your next reboot. If #2 is the wrong one, try #1.

[As you might guess, "browstat" has more parameters than it advertises
in "browstat /help"]

Interesting, is there perhaps a way to translate the GUID of the
"transports" into a network interface name so it can be positively
connected to the NIC?
A "hidden" command parameter perhaps?

The best I've been able to come up with is use Regedit and look at the
following key and subkeys:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\...

There is a "Service Name" and "Description" values that can be matched
up within each numbered key.

HTH,
