Local Area Connection Problem

[Richard]

Running Windows XP SP2. Broad- band modem always on, Linksys router.
Current on updates. Passes all virus, trojans, malware, etc. checks.

About a week ago, following a reboot, my computer does not automatically
hook up to my local area connection - no email, no FTP, no browsing, no
connection at all. Using the regular IP repair, ipconfig /release, ipconfig
/renew, netsh winsock reset, etc. - nothing accomplishes a repair or
connection.

Using Network Diagnostics for Windows XP results (in about four or five
minutes) results in a successful repair.

Another method of repair:
Control panel > Network Connections and clicking on Local Area Connection
status indicates "Connected" - except that I'm not connected. Clicking on
"Repair Connection" - no repair.

However, clicking on "Disable this network device" and then after waiting
for the disconnect status to appear, and then clicking on "Enable this
network device" - then wait. Suddenly I'm connected. Everything works
great until the next time I turn the computer off and reboot. (Sometime
necessary after updates.)

I would like to simplify my repair process. What are the command line
programs to accomplish these two operations?

So my question - to speed up this "work-around" what are the command line
programs to do these two functions? What is the name of the "Disable...."
program, and what is the name of the "Enable..." program . I've looked
under Windows folder and System 32 folder, and can't find anything likely.
Many of the name of the command line programs do not give a clue as to what
they really do.

Any help would be greatly appreciated.

Instead of just a looking for an (annoying) workaround, you should fix it.

Symptoms sound like DHCP...

Yes, sounds like DHCP problem to me too! That's what I'm trying to get
advice on. Any suggestions other than telling me I have a connection
problem probably due to DHCP?

By the way, do you know the command line programs to run in case I can't fix
it?

Thanks in advance.

Do the TCP/IP properties for the network device look good?
Settings in the router?

By the way, do you know the command line programs to run in case I can't
fix it?

Tried: ipconfig /registerdns ?
(Refreshes DHCP and DNS)

 

[Richard]

Thanks for the advice.

The TCP/IP properties look good (same when working as when not working).

Update: ipconfig /registerdns does not fix my connection problem.
Something is blocking the usual fixes as I described in my opening post.
After running the Disable and the Enable, all is functioning well. Until I
fix the underlying problem, this work around is not too cumbersome. Thanks
for input.
