Hi all, I am no programmer at all, but I have created these two scripts, that will notify me when problems with my dc's start occuring. The first script verifies the output of ldapcmp between the dc's, and sends it to my when the output shows a failure. This script runs on one dc only. The second script checks replication and makes sure it's output is as expected. If the output is unexpected, I am notified by email. This script runs on all my dc's. Again: I'm no programmer at all, but these scripts are running here, and they do the job. Perhaps somebody here can benefit from them as well. ldapcmp script: http://pastebin.com/UMseG27y showrepl script: http://pastebin.com/BKC0ktwS Regards, MJ
