If you don't use DHCP then you must keep accurate records
of your IP address assignments. If you have no such records
then you must start compiling a list right now. You can do it
by inserting this line into your logon script:

for /F "tokens=2 delims=:" %%a in ('ipconfig ^| find /i "ip address"') do
echo %%a %date% %time% %ComputerName% %UserName% >>
\\YourServer\SomeShare\logon.log

This is one single long line even though it may wrap around
on your newsreader.

Sort the log file to see duplicate address assignments.

For manual configuration there IS NO 100% reliable
method for this.

In a manual situation YOU are supposed to maintain
your own list -- this is part of the difficulty of using
manual (rather than DHCP) configuration.

You can use tools like the free NMap (from
http://www.insecure.org/ ) to 'discover' your in use
addresses but this is ONLY going to work for those
which are ON and ONLINE.

If you need to use net mapping software you should
copy and paste the lists into a file (text, Xls, etc)
and then start maintaining it over time yourself.

Use the NMap only to check for mistakes or for the
initial bulk of the work.
