DHCP Client starts okay but never sends a request...

Greetings:

There have been postings about some 3rd party apps
leaving a dependence on DHCP when they are uninstalled.
While this may be true, there is another problem. If you
stop and re-start AND there is a dependence problem, then
DHCP tells you there is a problem.

In my case, the DHCP client starts without any problems,
BUT there is NO DHCP traffic generated.

How do I reset/reinitialize/reinstall (FIX)DHCP?

If you go to a command prompt and run "ipconfig /renew" what error message
does it give you?

When you start the service and it does not give an error, that just
indicates that the service was able to start. It does not indicate that the
service was able to get an address, just that it is now in a state where it
can TRY to get an address. It is obviously failing for some reason. The
ipconfig command above should give us an idea why it is failing.

Also, do you have, or have you recently uninstalled, any 3rd party firewall
or antivirus on this computer? Post back with your reply and I'll help you
try to figure out what is breaking your ability to get an address.
 
Hi Matt,

I'm not able to access the machine at this time but I
think it states something like unable to renew address.

Also, if I manually configure the settings, including the
gateway, ifconfig /all shows the proper addresses BUT NO
GATEWAY. Therefore, I can't get outside my own net.

The only software that was uninstalled was some file
sharing program. I know ... this is the machine of the
daughter of good client and I just help him out with his
home net. I've tried for a long time to limit
her "activities" to no avail.

Anyway, the dependencies under the DHCP client, as
reported in the services app, are: Tcpip, Afd, and NetBT.

Is there something specific you are looking for?

Thanks for you help.

The dependencies of the service I don't think is the problem. I have two
suspicions of the cause of your problem:

1) A third party firewall has gotten into a weird state and is blocking
everything.
2) Uninstalling something has hosed winsock because it left bits behind

If the file sharing software was peer to peer file sharing software, then I
think we're looking at number 2. Some peer to peer file sharing software
has spyware that comes along for the ride. If you didn't get the spyware
cleaned out of winsock but deleted the actual files, that would cause
exactly what you are seeing.

To confirm:

Open up "winmsd", expand Components, Networking and click on Protocol.
Scroll through the list (it may be long) and see if any of the Names listed
there start with anything besides MSAFD or RSVP (items that start with "XXX
over MSAFD" or "XXX over RSVP" can possibly be trouble too). If so, and you
aren't using the program indicated, then you can rebuild the winsock
catalog. Note, there ARE legitimate programs that plug into the winsock
catalog, including some firewalls and parental control software. If you
rebuild your winsock catalog, it WILL break those legitimate apps and you
will have to reinstall them to fix them. If you're not sure what a
particular thing is, copy all the text in the Protocol window and paste it
in a reply to the newsgroup and I can tell you if its something I recognize
or not.

To rebuild the winsock catalog, follow the steps below (steps courtesy of
Ken Wickes):

The following instructions will rebuild your catalog
for TCP/IP. If you are using any other transports (If you don't know, then
you probably aren't) then you will have to reinstall them as well.

Remember that editing the registry improperly can render Windows unusable.
If you are not comfortable with editing the registry, then consult a
professional for assistance.

1. Backup and delete the following registry keys with regedit.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

2. Reboot

3. Go to the network connections folder, right click the icon for your
network connection, and select properties.

4. Click install, choose "protocol", and click "add..."

5. Click "Have Disk...", enter "\windows\inf", click OK

6. Select "Internet Protocol (TCP/IP), click OK

7. When the process in complete, reboot

Post back here if you have more questions or want clarification on anything.
If this doesn't work, then post back and we'll see what else it could be.

I think there have been some replication problems with the news server Dave.
If you replied to this, try another post. I've got the thread tagged, but
that all depends on the news server I'm looking at getting the post (its not
just one server on the back end).
