Strangely, on a CLEAN install of Plesk 6.5.2 on a VIRGIN Microsoft Windows 2000 Server, the fpmapping.dll ISAPI filter is not loaded. Would someone please look at their IIS Control Panel and look to see where fpmapping.dll loads? I'm going to assume that fpmapping.dll loads under the web site that has your virtually hosted IP address of your Plesk server (the "Physical Hosting" IP address). Would someone take a look under the ISAPI Filter tab and tell me if they have mapping.dll and the fpse dll loaded. And also the order or the dlls and if fpmapping.dll is loaded? The forum member's assistance is much appreciated. Let's pray that the forums stay even when this new Microsoft Marketing person has been hired. I fear that this person's first task is to remove any 'negative' or possibly 'negative' talk/help/etc about Plesk -- including the tearing down of this forum. --> That is another THREAD --> DON'T DISCUSS THAT HERE.
