Microsoft IIS 4.x

Please note: To meet the most recent security standards [1], we strongly advise to update all servers running MS IIS 4.x with the most recent Service Packs for Windows NT 4.
We also advise to perform an upgrade on the server, of the MS Internet Explorer to at least version 5.5 Service Pack 2.

Step 1. Install the Server file certificate using Key Manager

Go to Key Manager

Install the new Server certificate by clicking on the key in the www directory (usually a broken key icon with a line through it), and select "Install Key Certificate".

Enter the Password

When you are prompted for bindings, add the IP and Port Number. "Any assigned" is acceptable if you do not have any other certificates installed on the web server.
Note: Multiple certificates installed on the same web server will require a separate IP Address for each because SSL does not support host headers.

Go to the Computers menu and select the option "Commit Changes", or close Key Manager and select "Yes" when prompted to commit changes.

The new Server certificate is now successfully installed.

Back up the Key in Key Manager by clicking on Key menu> Export -> Backup File. Store the backup file on the hard drive AND off the server.

Step 2: Installing the Root & Intermediate Certificates:

Your Certificate will have been emailed to you. The email will also contain two other Certificates: UTN-USERFirst-Hardware.crt and Digi-SignCADigi-SSLXp.crt or
Digi-SignCADigi-SSLXs.crt - save these Certificates to the desktop of the web server machine.

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

> UTN-USERFirst-Hardware.crt
> Digi-SignCADigi-SSLXp.crt or Digi-SignCADigi-SSLXs.crt

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 specific root store (you may also want to read (see Microsoft KnowledgeBase Q194788):

Repeat the same for the Digi-SignCADigi-SSLXp.crt or
Digi-SignCADigi-SSLXs.crt , however choose to place the certificates in the Intermediate Certification Authorities store.

ServicePack 5:
Same as SP4.

ServicePack 6:
Same as SP5.

Reboot the web server to complete the installation.
