Thanks for the quick response Grigsoft,
I'm running the following command:
wndsync.exe C:\CompTest\1 C:\CompTest\2 /auto /scan /R /X"~* *.bak *.tmp" /XD"DfsrPrivate" /date /report C:\DfsReport.html
However this leaves the Synchronize It! window open, looking at the options I can't see a way to close it once the report has been generated, the detail under /show- seems to imply that the application won't open unless there is an error, but it appears.
This effectively creates the report I need, but if I'm automatically running 7 or 8 reports a day, I don't want to log in after a week to find I've got 40+ Synchronize It! windows open
