RE: Deleting a Reg SubKey

Greetings, I am trying to perform this task to delete a subkey and tried to use GPO to propagate it using startup, but didn’t work. I created a 2-liner batch file (*.bat). The first line was just echoing the hostname to a reg.log file and the 2nd line is “reg delete /f /v >> reg.log. I would like to keep track of successes and failures. My server is W2K3 and WXP clients. Need to get rid of HKCR\FireFoxURL\Shell\Open\Command.

I have read lots of stuff on the web as well as MS TechNet but did not find a feasible method. Can someone please share a technique. Much appreciated.
