Hi andyshowfan
It really would help if you could tell us your connection setup. If you're on a lan are you the 1st in line or ? Try very hard to find out what modem & router brand name & model number you use. Oh I just realised you're connecting from work. You may need to force ip within LW:
Force IP instructions & sample image Try & find out if you can if there's a firewall. If you're connecting from work it's hard to imagine there won't be some kind of firewall/NAT router involved.
Update your Java to 1.5 (take the JRE)
Change your options to manual connect. And then go to File & select connect. To find them go here & untick the option box: windows: Tools>Options>Connections
mac osx: LW Prefs>Connections
