lost workgroup with ISP Change-- HELP NEEDED ASAP!

[kdhl23]

This is the setup. The network functioned without a glitch. 3 Win XP machines and 1 Win ME machine. There's also have a Brother printer all computers can print to.
The ISP was changed to Verizon DSL. Their tech support got all the computers to the Internet. The workgroup doesn't show up in Network Places anymore. None of the computers can see each other which also means that there's no printing happening either (except the host machine)

Should the network wizard be run on all the machines again or is there something else that should be done?

Any help ASAP is greatly appreciated!

changing ISP has nothing to do with your LAN.....what you need to find on your LAN is to know which machine is your Master Browser.......Master Browser hold the list of you LAN computer and allow s for quick lookup of local computer......select one computer as master browser and fix the registry setting accordingly:
Here is how:

Also, you can use software like LANHelper to find out which machine is master browser on your LAN (I would suspect that all of them will report as Master Browser and that's the reason none of the work station will allow other to become the list holder or master browser)

Apparently what the new ISP had to do with configurations and so forth changed settings and removed the router previously used... verified all the computers were in same workgroup and had seperate names... ran network wizard on all and voila'!
