Hi Johnathan,
It could be that Warcraft III is attempting to connect to one of the following AD servers that Blizzard included in their Warcraft III patches (since like v1.21 of like 1 year ago):
madserver.net
OR ad.madserver.net
OR imp.madserver.net
OR media.madserver.net
OR locate.madserver.net
If these AD servers are causing the problem, downloading & running the following batchfile in Windows should resolve the issue:

All it does is it lets those AD server addresses resolve to 127.0.0.1 by adding the entries in %windir%\system32\drivers\etc\hosts
