I have a 2003 server installed by some IT company over a decade ago, somehow they came up with this brilliant idea of using a public address for the internal network 200.200.200.xxx
I came across this server about 3 years ago, but by then, AD, DNS. ES are all already running, making matters worst, they also have Avaya IP phones and another bunch of IP related software installed.
I tried to fool the OS by changing the router IP back to a non-public IP, this allow the install stage through but then it can no longer find the old server name , kind of expected but I am desprate.
There are also around 40+ stations with a bunch of bespoke software that were installed on single user profile (not installed for All users).
I know I am asking for a miracle by the look of things, but is there anything I could try or a way to bypass the checks ?
Thanks as always.
