... tracing the route of the computer name fails, yet IP is fine.

Point the machine name to the known IP in the hosts file on all PCs.

your dns, hosts file and or netbios are all screwed.

I was going to break it more gently

Additional information for this fiasco!

I have a wireless laptop that can be used to connect to each site (5).
I use a nifty piece of software called "Mobile Net Switch" which can have multiple settings to connect to different network. Basically when you change site you can activate the sites settings to change it for that site. (i'll post details if people are interested in the program...)

Anyway...

The site i was at yesterday where all these problems are occuring with unable to ping computer names... was occuring also on my laptop...

Now i'm at HQ and the settings have changed slightly, weirdly... i am now able to ping computer names at this site...

The only changes though are the IP address and the Default Gateway.

At the (broken) site, i've tried changing the IP's around in case it was IP related between a working pc and a broken one. This fails.

We've tried translating the computer name to IP in the host file but this doesn't seem to work either.

(anyone able to tell me what LMHOST does? It is enabled...) (LMHOST is in the advanced tab on the TCP/IP properties - wins tab)

LMHosts is a lookup file for resolving LAN Manager names and IPs - I'm sure someone will give a better more accurate explanation.

weird


Is there a DHCP, DNS and WINS server on your network or is everyone just discovering each other on the network on their own?

Probably not if you're using mobile net switch.... at first read it just sounds like the dns and NetBIOS name cache tables were wiped and you're not discovering the machines properly.

Is the DNS server internal to the network and does it have the PCs in its area listed?


Maybe try this out to get things situated: http://www.famatech.com/products/utilities/lanscanner.php

I *think* it pulls the machine the name from the machine (nbtstat -a ), but I can't remember.  I've used it in areas w/o any structure to find things on the fly.
