I see James mentioned a CLR stored procedure, what is it?

I've also tried to follow the instructions in the article to access the C:\BlackBerry folder on my pc so I looked up my pc's IP address by typing "ipconfig" in the DOS command window and then entering

http://10.10.137.152/blackberry/blackberry.asp?helpLevel=0

in the blackberry browser but I get HTTP Error 404: Not Found
