XP Network - Couldnt Map The Shared Documents Folder On Server

I have a problem trying to Map an XP drive on my Vista Home Basic Laptop that is proving a nightmare: We have several computers on our netwrok, including the XP server itself where we have our shared documents. (place where all shared files go that we want other users to see) I have mapped the same shared docs folder accross all of out XP machines. Plugged my Vista Home Basic Laptop into our network, couldnt map the shared docs folder on my server. After reading many how to's, i followed this guide: Microsoft Corporation I have downloaded and installed the LLTD responder on the server with XP All computers were restarted, now when looking on the laptops "Veiw full map" I can see FILE_STORAGE (our server) but the guide above says right click on the computer running XP, however when I do this nothing happens, it is a solid icon and clicking it does nothing.

All computers including the laptop are on the same workgroup The laptop has appeared when looking on the XP machine under viewing the network I have opened ports UDP: 137, 138, 1900 and TCP 21, 139, 445 2869 We have AVG Antivirus and Firewall on all machines including the laptop. AVG does not allow you to open ports, so the above ports were opened on my router. When I plugged the laptop into the network AVG asked me to select a profile, I selected ALLOW ALL for the time being as "Computer In Domain" was not there to select. The vista laptop has Network Disc. ON, File Sharing ON, Public Folder Sharing ON and Printer Sharing ON One thing I couldnt get my head round was the differance between Workgroup and Network. The workgroup is the same on all computers, but I wasnt aware that I had ever given a "Network" name on any of the XP machine. Vista did ask for a "Network" name. For safety i put the same name as is in the workgroup. Anyone any ideas, im desperate?
