Windows 7 networking fails after any change

I am supporting a person remotely whose machine is doing something I haven't seen before.  What I have noticed is that whenever I make any change whatsoever it locks me out of the machine and she has to unplug the network cable and reconnect it in order to get back on the Internet.  There is nothing of use in the event logs other than DNS lookups failing.  

I have assigned a static IP to it and this seems to do away with the requirement of unplugging and reconnecting, but any change still knocks out network connectivity for 30-60 seconds before it returns.

Any ideas?  TIA

Try to change Administrator password by logging in one of the administrators account

Start>RUN enter 'control userpasswords2' > press OK

Reset the Administrator password. disconnect it from internet and check if lock out still occurs

I would also like to ask the paswword age specified for that account.  Any changes made in the group policy settings of the computer which would enforce this ?
This can be altered by going through cmd-run- computer configuration-windows settings-security settings- account policy - password policy and account locout policy.

Change the thresholds here and check if this issue re appears.

My bad.  By locks me out I mean it breaks networking altogether.  The user experiences the same thing.  The machine functions fine with the exception that she loses access to the Internet and any other local network resources for 30-60 seconds and then it comes back.

OK, problem solved!  Turns out there was a second router between the computer and the DSL router from  Verizon.  The user told me sort of by accident that it was there when talking about a different thing.  

Note to self:  Assume nothing.  Get all the details, even if you think you already have them... ask again!!

Thanks for the efforts folks
