Installing your Certificate on Microsoft IIS 4.x

Intstalling the Root & Intermediate Certificates:

Your Certificate will have been emailed to you. The email will also contain three other Certificates: GlobalSignRootCA.crt, GlobalSignPartnersCA.crt certificate and ComodoClass3SecurityServicesCA.crt

It is essential that you have installed these three Certificates on the machine running IIS4. You may also download them below:

> GlobalSignRootCA
> GlobalSignPartnersCA
> ComodoClass3SecurityServicesCA

Once you have installed the Certificates, restart the machine running IIS4. You must now complete one of the following procedures - the procedure you follow is dependent on the Service Pack that has been implemented on your machine running IIS4.

ServicePack 3:
Install the above certificates in your Internet Explorer by opening each certificate and clicking "Install Certificate". You may then use this IISCA batch file to transfer all root certificates from your Internet Explorer to the IIS (see Microsoft KnowledgeBase Q216339).

ServicePack 4:
Install the above certificates manually in a specicfic root store (you may also want to read (see Microsoft KnowledgeBase Q194788):
