Vista Default Gateway problem

Hello,

I have a weird problem.  My laptop (Dell Vostro 1510 Vista Ultimate x86 SP2 beta) keeps reverting to a weird Default Gateway when I boot it up or come out of sleep mode on the wireless connection.  

Wait, let me back up.  A week and a half ago I was at a business training class in Boston when they let us plug into their wired LAN for internet access.  I plugged my computer in to the network and couldn't get online right away.  I had to do an ipconfig /release and /renew to get a proper IP, subnet and DG.  Everything was fine and dandy when, about an hour into it, the IT guy walks in and asked if anyone had a computer named "vostro1510".  I slowly raised my hand and he said "it seems your computer is taking over the network as a DHCP server and is handing out IP addresses".  I was baffled.  I'm not using internet sharing on either of my internet connections and I'm setup for dynamic IP.  He checked on my computer and sure enough, when I clicked on Network Computers and Devices, a host of computer names popped up and apparently My laptop had taken over as the DHCP server.  I've never installed DHCP server software and I dont think that Vista Ultimate has the capability.  I could be wrong.

So I was barred from their network and now I have this problem.  Whenever I come out of sleep or turn my computer on, the wireless connection defaults to the same Default Gateway that the aforementioned company was handing out.  It's the number 169.14.244.1.  I know, the 169 makes it seem like an autoconfig address, but it's not.  So now when I turn on, I have to /relese and /renew to get it working.  Why is this happening?  I've searched and searched, but the only thing i've been able to find is about the problem that SP2 fixed when computers default to 0.0.0.0.  Any ideas?  Why is my computer remembering that obscure Default Gateway?  It's been over a week since i was connected.  Also, why is my connection specific DNS suffix still say the company name?

While you're at home. Which router are you using?
Can you tell me does is it a plain DHCP (with on and off options) or you can setup it (dhcp range etc).
Either disable the LAN interface, or go into it's TCP properties and switch to static IP (don't forget to remove DNS info in advanced properties, too). This should remove the old settings without doing any harm.

At Home I'm using a D-Link Gamerlounge Router.  I can set the dhcp range on it.  

I don't want to set it to static, because I hop from network to network all the time at work.  Also, I've already removed DNS infor in the advanced properties on both connections.  They were populated with weird IP's but they're clear now.
Of course you can enable the interface and/or DHCP again after you've done my suggestions.
If you've made a DHCP setup on the router, in your network connection properties select to automatically aquire IP address along with the dns server.
Ok. I've been out of town sorry. I have dhcp enabled on my router and both ip and dns are setup to acquire automatically on my laptop.  I just can't figure out why my computer would save a gateway and dns suffix weeks after using one only temporarily. And even when I was on their network, I was using auto configure. No static.

Your (inactive) LAN connection sticks on that IP address. This happens sometimes. You can see all info if you go into a cmd.exe and type
netsh interface ip dump
Ok, weird.  I got my new iPhone and connected it to the Wifi at my house.  Then, later, out of the blue, my iphone stopped working on the internet, so I checked it out and the IP address it was reading was one with the weird Gateway that my Laptop has been dealing with.  The Iphone pulled an address from my laptop.  Why?  

Anyways, I uninstalled/reinstalled the drivers for my network adapters and I havent had the problem since last night, but i'll keep you posted.
That looks like PNRP is active, as you do not have either ICS or DHCP server active (and DHCP server is not part of Vista Ultimate, as you stated correctly).

Ok problem has not recurred since reinstalling nic drivers. Thanks!
