Drew:   MyDomain.com (my DNS provider for 7 years now) says they
cannot or will not lower the TTL. I now believe they are the same
company as Dotster and ZoneEdit. So, the 3600 TTL I will need to live
with, and I will try to get in here in the morning, about 3 A.M., to
try this again. Hopefully I can test on the other server, after I
switch the "A" record, wait one hour,  check the authoritative name
server to be sure it points to the other server and then flush the DNS
cache in my IPCopbox.    Lanny
