I Need to block a range of IP's from using my service, and it's a big range, so i don't want to add them 1 by 1.

I am using MS WINDOWS SERVER 2003, IIS 6.0

You can restrict access to your site through TCP/IP address restrictions.
for example, if you want to block ftp using an ip range, then you can deny all access to your FTP site (FTP site Properties | Directory Security tab), then grant access to the IP addresses or address ranges you want. This way, they will be the only ones with access.

To deny access to resources for a group of computers

In IIS Manager, expand the local computer, right-click a Web site, directory, or file you want to configure, and click Properties.
Click the Directory Security or File Security tab. In the IP address and domain name restrictions section, click Edit.
Click Denied access.
When you select Denied access, you deny access to all computers and domains, except to those that you specifically grant access.
Click Add.
Click Group of computers.
In the Network ID box, type the IP address of the host computer.
In the Subnet mask box, type the subnet ID for the computer you want grant or deny access to.
Click OK three times.
