I have scripted the subject report, in a format similar to:
<b>192.168.1.10 \\ALRMP                  Jerry
192.168.1.20 \\DELL                   Jennifer</b>
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:
