There's an entry here named restrictanonymous - each time I've had a problem with an XP machine losing connection with the network, I've found this key set as value 1. It should be set at 0 (zero). When I've set it back, it instantly restores communication.

Then I started poking around the Network and Sharing Center on my Vista laptop and now I feel the problem could lay there: it appears that the computer (Vista) is trying to connect to another network, possibly a neighbor's wireless router. In the pictures at the top of Network and Sharing Center, the network link between my computer and "Internet" is showing as WLAN_AD (my wireless network) then switches to "Identifying...", then "Multiple Networks". This keeps changing over and over, appearing to try to resolve the network connection. Although, I'm clearly already connected to my WLAN_AD wireless network and have access to the internet!
Additionally, now when I view my network on the Vista laptop I can actually see my XP machine but I can't access it: Error code 0x80070035 "The network path was not found". And on top of that, my Vista laptop isn't seeing itself anymore. It seems like every day this goofy situation with my network changes, or gets worse...you decide!!!
Anyway, is there anyway to make Vista stop trying to identify and/or connect to the other unknown network? Or am I barking up the wrong tree? What I would really like to do is delete all my existing network settings and start over fresh...any suggestions?
Thanks to all for you replies...hopefully we can figure this mess out together.

Ok, well it appears I'm out of luck here, I guess. Last-ditch effort...any ideas on how I can reset all my network settings to default so I can start over from scratch?
Thanks.
Thanks.

Hi Jonnie_Cellmate,
Sorry I've been away for a bit, but to answer your earlier question you would place the return from the ipconfig/all command between code tags: [ then the word CODE then ] (ipconfig/all contents) [ then / then Code then ]
It will look like something like this when you do a Preview Post:
Please take care to delete your directory path (C:\Documents and Settings\...etc), and I also delete the hostname.
I'll post back later after I get a chance to go over what you just posted, but I'll likely ask to see that info anyway.

With your connection to the internet disconnected, but your router still up and running, temporarily disable an software firewalls, virus scanning and any other transmission security software you're running on both machines, and then see if the can communicate as a stand alone home LAN. Remember to reactivate your software before connecting back to your ISP! And yes, please go ahead and post the ipconfig/all info too.

Hi aeinstein. I followed your instructions quoted above and the Vista laptop and XP desktop still cannot see each other on the network. I'm able to ping both computers from one another, however, not always. For example, when I ping the XP machine from the Vista laptop the ping fails at first. It will eventually work if I ping the Vista laptop from the XP machine first, which works fine. I'm not sure if this is relevant to the situation, but it's almost as if the Vista laptop doesn't see the XP machine until the XP machine sees it first. Anyway, I'm posting ipconfig/all info for both machines below. Thanks so much for your assistance!

Under network and sharing centre make sure the network type is set to home and that discovery is enabled

Network discovery is enabled and the network type is set to private (as opposed to public). I don't see anything that refers to a network type of "home".
Private is fine, if you choose home/work instead of public internet when it pops up, it chooses private. There is no functional difference between home and work locations on the home editions.

DHCP is disabled on your notebook. That may be an issue. Try turning it on (should be an option on the settings for your wireless NIC).

Well, I enabled dhcp and still no luck. I'm so at my wits end here! I understand that a secure OS is important, but why does Microsoft have to make it so darn difficult for XP and Vista to play nice together?!!!
