It should NOT take anywhere near a minute on a machine that fast. The
original NetReg server (still running on the same hardware) is a Pentium
Pro 200Mhz system with 32Mb of RAM!!!! And it loads in 3 secs.
It sounds to me like a timeout problem. There may be a DNS timeout of
some kind. You may want to put a sniffer in front of the server to see
if it's trying to communicate with something that isn't there or
listening.
