ICS Host issue after reboot

Hi, I'm looking for some help with a tempermental ICS
Host. I run the network wizard and set up ICS ... all
works well with the client being able to access the
internet. After rebooting all is bad ... the client can
no longer access the internet. I rerun the wizard ...
1st time it fails ... 2nd time it completes okay and all
is well again for the client i.e. it can access the
internet. Immediately before rebooting (and after
startup) I have run an "ipconfig /all" and have noticed
that IP Routing Enabled is YES prior to reboot but is NO
after. I'm unsure if this is a red herring or not. Hope
someone can help me.
Cheers,
Tony.

I've seen several reports of the problem that you describe, Tony, and
the key could be exactly what you discovered: IP Routing Enabled
should be YES, but it gets set to NO.

I suspect that a program that runs automatically when the host
computer starts up is responsible. Try disabling all non-essential
items in Start | Run | Msconfig | Startup on the host, then reboot it
and see if the client has Internet access. If it does, enable host
startup items one-by-one, rebooting after each one, until you find
which one causes the problem.

Please post a reply to this message in the news group if you find
something.

Steve,

thanks for the tip ... now my challenge is to figure out
what is essential and what isn't :) ... good luck to me.
I'll post a reply to let you know how I get on.

Thanks again.

Well not being able to determine what is essential and
what isn't I thought I might as well start with
the "disable all" option ... IP Routing was YES before
the reboot and it was NO afterwards.
I then tried disabling all NON-MSoft services too ...
same result YES before reboot and NO after.
Is there anyway to manually set this parameter ... I can
get it set "by magic" using the wizard or by choosing to
share the internet connection though I can't find where I
might get the setting changed elsewhere.
Is it correct to be focussing on this parameter? Or could
this observation be leading us away from the real problem
(love to know what it is).
Do you have any more suggestions?
Cheers, Tony.

Darn, I was hoping that we could find what's turing off IP Routing.
I've been using a registry monitor program (Regmon, free from
www.sysinternals.com) to see what effects enabling and disabling ICS
has on the registry, and I can't find anything that's clearly related
to IP Routing.

Try setting registry key "IPEnableRouter", as shown on this page:

http://www.winguides.com/registry/display.php/1171/

I don't think that it will help, because enabling and disabling ICS
doesn't seem to change the key, but it's worth a try.

I'm afraid that's the only other suggestion I have, Tony. I've
referred this problem to people at Microsoft in the past, and no one
there has come up with an answer.

Thanks again Steve.

I already had a registry setting and it was set to zero.
So now an IPCONFIG /ALL looks exactly the ame before and
after a reboot. The only problem is that the client
still can't access the internet after I reboot ... grrrrr.
I still have to run the wizard each time to get it going.

Anymore thoughts?

Tony.

Did you try setting IPEnableRouting to 1?

As I've said, I've referred this problem to people at Microsoft in the
past, and no one there has come up with an answer. I'm sorry.

Steve,

sorry I wasn't quite clear before was I. Yes I set it to
1 and that made my IPCONFIG look the same before and
after reboot i.e. IP Routing is enabled both before and
after reboot now. Unfortunately this hasn't helped the
ICS side for the client though. If you've run out of
ideas is there an open issue with MSoft that I can track?

Thanks for your time.

Happy New Year,
Tony.
