Hey! This is the Win95 area. Get out of here with your XP questions! ;-)

I think this advice is wrong. If you run services on a pc, you better set
the IP configuration to static. Use an IP number outside the DHCP range
which apparently starts with 100 on your router. So 192.168.1.10 could be a
good candidate. The subnet mask would be 255.255.255.0. The default gateway
and Prefered DNS server should be copied from your current configuration.
(You know where to look for those?)

If you have made special adaptations to your routers/firewall configuration
to point to the .100 address, of course you have to change those to the new
IP address.

I don't know anything about the Wallwatcher and Getlog programs, but maybe
they also need to be told to use the new address. Or maybe just reboot
after the IP configuration change, will fix this automagically?

Does this make any sense to you?


Bye, Wilfred.
