OWA and IIS4.0

Hi All

we have OWA installed on our exchange server. the exchange web site by default is installed under the defualt web site under IIS. i want to move the exchange site to it’s own directory so i can turn off the default site. I have setup the new virtual directory however in the ISAPI filter i added the exchfilt.dll from the system32 directory, but it appears with a red arrow down, indicating the dll is not correctly installed. has anyone come across this or has anyone setup a new directory for exchange OWA under IIS.

any help would be great
