I have installed Posting Acceptor on a NT Server running IIS 4.0 and Site Server 2.0. But whenever I run the asp page containing the upload control I get an error message saying &#039The selected web server is not compatible with the selected service provider&#039. Visual Studio 6.0 is installed on the same server but I only selected Visual Interdev to install. If somebody knows what is wrong please, answer on this message board or contact me at puertas@iname.com. Thank you in advance.<BR>For those who want to install Posting Acceptor I recomend the article by Susie Adams at the address below:<BR>http://www.zdjournals.com/asp/9908/asp9981.htm
