Installing intermediate certificates for IIS 7.0

In order to import intermediate certificates into IIS we will use the local Windows Certificate store - to do this we will firstly launch mmc and add the "Certificates" snapin - although make sure that it is added as under the "Local Computer" account:

Now we will browse down the tree until we find "Intermediate Certificates" > "Certificates" - right hand click and import - dependent on the format of the certificates you might need to enter *.* to see all file formats while browsing for the certificates. Finally import and reset IIS:

iisreset
