My computer is running Win 2K Pro on a peer-to-peer network with XP machines. Until recently I was able to see all the computers in my workgroup and access their shared folders but suddenly something has changed and I can't see them and their printers are not accessible. Could this be something to do with Lavasoft (recently installed) or Spybot?

can you still browse the internet?  can you ping them by IP address? can you ping them by computer name?  are you running a software firewall?

type "ipconfig" on a computer to get it's IP address

then from the 2k computer, try and ping the other computers that can't be reached.  Make sure you try both by IP address and by computer name.

Yes, because you can read this. Everything was working fine until a couple of weeks ago.

disable your tiny personal firewall.  then try "ipconfig" again.  Is that all it says?  Media State: Lan cable disconnected?

I disabled the firewall. Yes, it gives the IP addresses and then says that the cable's disconnected. Is it possible that the connection's broken for the lan but not the web? The machine is connected directly to the hub and so are the others

I would have to assume that it has two LAN connections and you are only using one of them.  Otherwise, I really don't know.  So know you can ping the other computers but cannot browse them?

That's right - pinging is ok. There's an ethernet connection in the computer and one in the docking station, so only one's in use at one time. I can ping the other computers successfully but they won't show up in network neighborhood and the printers won't connect. Everything is shared correctly and all the protocols are present as far as I can see: Client for Miscrosoft Networks, File and Printer Sharing, TCP/IP. All the computers are in the same workgroup and Netbios is enabled in WINS.

Everything is running again - it must be the firewall. What entry would cause the problem?

If you can, please post "IPCONFIG /ALL" for each of the 3 machines.  you can remove anything that you feel is a security risk to put on the internet.

netbios browsing and microsoft networking use ports 137-139 and 445.  I believe that's about all of them.  Your firewall is blocking them.  Not real familiar with that brand so I couldn't tell you how to fix it.  But you need to allow/open those ports.
