Hi! sorry for my english.

I have a need for a batch file that is EXECUTED by windows task manager, in it it will PING several machines every 60 seconds, but I need to make it do that for just 12 HOURS. I tried to search for a post here but I could not find it.

I'm using choice to give the PAUSE between pings, but I don't know how to make it play for 12 hours.

Hope you can help me.

I use windows vista.you could try having a statement something like: 'set startTime=%time%' and then find the differance in the current time and %startTime%, 'if %diffrence% LSS 12 goto :loop'. (It might take a few trials to get it working correctly.) Hope this helps!Which 12 hours? AM? PM? Some other mixture?It will start aprox 4 am and finish 12 hours laterCall this batch file gethour.bat and add a line in yours that looks like this, to quit once it reaches 4pm.
