I have scripted the subject report, in a format similar to:

192.168.1.10 \\ALRMP                  Jerry
192.168.1.20 \\DELL                   Jennifer

The script uses SOON and SLEEP from the Server Resource Kit Supplement 4.

If you don't have SOON, create your own.

if you don't have SLEEP, use a PAUSE.

There are two (2) batch files required. The controlling script is WhatIpDCsubmit.bat. The syntax is:

WhatIpDCsubmit WhatIpDC.bat ReportFile DC1 \[DC2 DC3 ... DCn\]       where:

WhatIpDC.bat	is the full path to the WhatIpDC.bat file.
ReportFile	is the full path to the output report file.
DCx	is the ComputerName of each domain controller.

NOTE: You must adjust the SLEEP time (currently 900 seconds (15 minutes)) to insure the scheduled jobs finish.

WhatIpDCsubmit.bat contains:

@echo off
setlocal
if /i not \{%3\}
\{\} goto begin
:syntax
@echo Syntax: WhatIpDCsubmit WhatIpDC.bat ReportFile DC1 \[DC2 DC3 ... DCn\]
