Anyone else having problems?
I've had to hard code the IP address (once I found it) into my hosts file in order to connect without using a proxy.
Happens on more than one PC so it isn't the PC, and other lookups work fine so it isn't my router. I suppose it could be my ISP's dns server.
If anyone else is having problems a temporary workaround is to add this line to the hosts file ("c:\windows\system32\drivers\etc\hosts" as default for Win2K & XP, c:\windows\hosts for Win98 and ME).
