On the windows side, I'd use a simple for-loop.
Is it a windows domain? Or local users?

"Domain Controller (Netware 5/6)" - your domain controller is not windows?

I had just listed some of the services we have on our environment.  It is a mutli-platform environment.
We do not have  Windows Domain.  We have  Novell.

I just wanted to know a simple way to change the Admin  passwords on:  Windows and  Linux  systems.  - Thats all.

Ok, understood.
If you have many servers, I assume, for better management, you have setup the same admin password on all machines and you want to change that one on all servers to the same new password?

Then I'd use psexec, download it from here: https://technet.microsoft.com/en-us/sysinternals/pstools.aspx
Logon to one server with that common administrator, open a command line and launch
for /f %a in (c:\temp\servers.txt) do psexec \\%a net user administrator newpass

Open in new window

Note: c:\temp\servers.txt is a list with servernames like this:
server1
server2
someserver
...

Open in new window

Great the SysInternals is helpful for Windows (we cannot have the same password on 2 systems - each system will have a different password).

However any suggestion for  Linux systems?
