PDC's DHCP screwed up my laptop's name resolution

Thanks for your post, Aaron. I was hit by the same thing - it was getting frustrating not being able to use machine names after getting home from PDC. Simple name resolution was simply not working.

If anyone else is having this problem, run ipconfig /all and check your Node Type. Mine was flipped to something like “Peer to Peer“. The following registry entry (followed by a reboot - bleh) switched it to Broadcast and made things work again. I've not spent much time studying the name resolution protocol that MS uses, but I know I don't have a WINS server at home, so I guess Broadcast makes the most sense for me (if you know better, please post a comment here :-)

Here's the registry key you need to tweak, assuming you're running XP:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters

Add a DWORD named value called NodeType and set it's value to 1. Reboot and check your node type again - it should be Broadcast, and name resolution should start working again for you.

For more info on this registry key, see kb article number 160177.

Thanks again, Aaron :-)

Yes, I have had the same issue today and hadn't solved until I ran across your blogs. Thanks for the help.

You are my hero! I couldn't figure out the problem and was going out of my mind! I realized that I could connect to network shares using IP address, but net names were no good. I'm so glad I came across this post!

Thanks again for posting. You've made things all better!

Do you happen to know the trade-offs between use B-mode vs H-Mode or M-Mode? I'm having exact same problem and glory be somehow my notebook PC got set into P-mode (peer-to-peer) which apparently causes PC name resolution to not work unless... (unless what, I don't know), but I do no that PC name resolution won't work on a home LAN with node type of peer-to-peer (P-mode) and no WINS server.

I haven't done the research, no. If anyone can point us to a link that explains this in depth, leave a comment please :)

I have a wireless network set up in the country from a satelite connection. When I use my Laptop on it all is fine. Return to work on Monday and cant see the network drives. The node has changed to peer to peer, I know the hack to change it back but any ideas why this happens and how to prevent it.

Thanks,

Larry
