Compatibility Xymon 4.2
Requirements dcdiags and netdiags from the windows support tools and a Xymon client
Download None
Last Update 2008-08-26

Runs the support tools dcdiags.exe and netdiags.exe and reports the results to Big Brother or Xymon. These two tests are the basic tests to confirm the correct operation of Active Directory.

Client side

Save the script, dcdiags.exe and netdiags.exe into the same folder. Add a sceduled task to run the script as required at your site (once a day?).

Several errors have been hardcoded to be ignored. You may need to comment these out.

Server side

none
