If you have your local web open, the remote server address is that of your
website eg
http://www.yoursite.com, or the FTP location (if you don't
publish using the server extensions - contact your host if unsure of the ftp
address). FTP address could be something along the lines of
ftp://ftp.yourwebsite.com
If you have the live site open, or are publishing by FTP to your computer,
the location is the folder where your web is located
eg "x:\pathtoyourwebsite\yourweb\" where "X" is your hard drive and
"pathtoyourwebsite\yourweb" is the location where you store your websites.
Hope that assists you.
