DHCP Problem

I'm trying to get an MS laptop for a Redmond MS non-technical employee
working on their home WiFi network. The laptop works on the MS internal
network both on WiFi and ethernet cable. It's XP SP2.

I have previously got the same laptop(pre-SP2) working on the same home WiFi
setup but MS techs had to reinstall XP for other reasons. MS's internal
help folks wont help with home networking.

Previously all one had to do was turn off the internal MS proxy server
settings in LAN Settting and then the home WiFi would work. Now the same
changes don't work/help. I still can't get anything to work.

That exact same failure happens in all the cases I've tried:
1)WiFi with 128bit WEP
2)WiFi no security
3)hardwired ethernet
It wont do DHCP. It wont get a new IP. IPCONFIG releases to 0.0.0.0 but
renew fails and one gets back the same IP that was left there from the MS
hookup. The laptop says its trying to get an IP but it fails. The same LAN
cable will provide an IP to another(non-MS) laptop and desktop. The WiFi
will supply an IP to another(non-MS) laptop. IPCONFIG on the WiFi always
says that media is disconnected regardless of the fact that XP reports
having found the home WiFi network.

I'm unable to conveniently turn off SP2's firewall as Group Policies is set
to prevent that. Also I've noticed someting in the System Tray about ISA
server. Turning that off doesn't help.

What's likely keeping this laptop from getting a new IP on the home
network????
What are obvious debug steps or experiemnts to solve this?
IPSEC?

In your case, it might be easier to pick up a raw, shelled egg with
chopsticks than to get an ms laptop for a redmond ms non-technical employee
working on their home wifi network.

Really? You have previously got the same laptop?

Disingenuous.

Get a sense of humour.

From birth.

The service in this place sucks.

That could change very rapidly.

I've turned into the kind of person I'd never be friends with.

Help?

What's happening, bro'?

What answer would please you the most?

You know, it almost makes you feel normal.

What happens if you enter the IP information manually for the RJ-45 /
Local Area Network connection, then plug it in?

Do they have internal tech support? (yes I did read further down)

Workgroup / domain names?

That's funny, they (MS) will mess up home settings with introducing
patches and SP's.

NetStumbler, http://www.netstumbler.org/

>3)hardwired ethernet


It's assumed on the laptop that networking device (1) and (3) are
installed by MS, can you put in another NIC, say hardwired you have a
bit more control of?

With (3) do you get link light on the PC/Router ends?

Try (3) again, but manually specify IP settings within the range of the
home router.

Usually with issues like this, I use a repeater and a 2nd PC running a
packet sniffer to see the outgoing DHCP requests (and any replies) from
the problem PC.

On a setup like that, someone else's group policy / setup I wouldn't
install the sniffer capture driver / sniffer app anyway.

A common issue, see www.google.com for many different comments on 'media
disconnected' ,
http://www.google.com/search?q=windo...s+disconnected

>having found the home WiFi network.


The devices are enabled for connecting?

You are logging on to the laptop at home using an internal MS network
account or a local account?

ISA server is firewall / web cache etc.
http://www.microsoft.com/isaserver/default.mspx
so at home you most likely don't want to connect that way.

It may even be a policy / account restriction.

Packet sniffer, to see whats happening.

See last comment above.

>IPSEC?


What is IPSEC, http://webopedia.com/TERM/I/IPsec.html

A very handy utility for multiple network configurations is Netswitcher
, www.netswitcher.com however the wireless fancy bit is an upcoming new
feature.

Inet connectivity is the issue. How do the above relate to that.?

Inhouse security and proxy configurations are the more likely reason. The
non-MS laptop that I described that does work also has SP2 and uses SP2's
firewall and works flawlessly.

Thanks, I'll investigate that.

I'll consider that.

Yes.

I'll try that. If that works then what's killing the DHCP?

Could you describe that setup in DETAIL, please.

I don't follow. You wouldn't install the sniffer on the failing MS laptop
or you wouldn't install the sniffer on "2nd PC running a packet sniffer"?

Rephrase that please?

There's no accout to log onto on the home network. The standard username/PW
that's used at MS(work) is used at home or with no network connection which
is the usual for laptop security.

That would be an internal Microsoft employee who doesn't have access to
Microsoft support personnel for this?

That won't be answered by specifying the IP manually, it will prover
lots of other stuff works.

Instead of router ----- pc you do this ,

router --to --- repeater --to--- pc with installed sniffer software.
on another port on the repeater --connect--- pc with problem

The router is usually a switch and it seperates traffic going to / from
each port from the other, the repeater is a common link so all traffic
to from the PC with the problem can be see by the sniffer.

"I would install" the sniffer on the failing MS, if I knew more about
it, had local admin rights, was sure that I could repair any issues, if
there were a problem. Although I have never has a problem with the
WinPcap driver, it's installed into the network stack.

Basically my point there is (as a IT person) I don't have much time or
sympathy for those that mess up 'works' laptops with 'home' networking.

Using the repeater method, install the sniffer on the 2nd PC. It always
works.

The devices are enabled , for the permissions you log on with.

Fair enough we have domain / work account and local admin to let heavey
users reapir / update / insall.

Don't know, don't uses ISA so don't know what to disable.
