I have Back Office 4.5 and I was wondering how to block external IP addresses from connecting to my server. Is it something that I do in the command window in NT or is it something that is done in the management console for MS Proxy Server?? I'm looking for step by step instructions...

thanks

firewall is the best device to block external IP addresses to your server.

Hi,
This is based on IIS 4.0. with NT 4.0/SP 6a.
A box that IIS is installed, click start,
Programs, Windows NT 4.0 Option Pack, Microsoft Internet Information Server, Internet Service Manager. Under Internet Information Server, you will see FTPservice and WWW service. Right-Click one that you want to block to specific IP, Click properties. Click on Directory Security tab.
You can see IP address access control(at the bottem). Click on it, you can put IP and selecte either Access or Dinied.

Good Luck,

YOU SHOULD CONSIDER A FIREWALL IN ORDER TO BLOCK IP ADDRESS, UNLESS YOU WANT TO EXCLUDE ALL EXTERNAT IP ADDRESS, TASK THAT YOU MAY ACCOMPLISH IN THE SECURITY CONFIGURATION TAB OF THE IIS ADMIN, AND ALLOW ONLY A FEW, BUT IF YOU HAVE A LARGE LIST, THESERVER PERFORMANCE WILL BE DEGRADATED MORE THAN YOU EXPECTED.
