There’s no place like a dual home

Had a call this weekend from a confused customer, he was trying to replace a store server for his customer and it just wouldn’t find its way out of the network onto the internet. What made it strange was that it was able to talk with all the machines on the local LAN we could even VNC to it from the old windows 2000 “server”???

It did have a strange local IP address range 192.169.32. but its subnet and gateway were the same as the old server we were connected to so it should work, right?

Can you guess ??

I spotted that the old Windows 2000 box had 2 network cards “local” and “Internet” installed DOH!! Its dual homed, a little strange for a 5 client LAN but still I have seen stranger.

Solution

Added the “Internet” subnet to the additional IPv4 settings on the new server and suddenly its on-line and a happy customer.

It was great to see Windows 2000 again such a simple interface it was like seeing an old friend…..but why was it dual homed still escapes me.
