Resolution
A. Exporting certificates from Netscape:
1. Go to Netscape Navigator and click the "Security" button in the toolbar.
2. Click "Yours" under the "Certificates" item.
3. Select the certificate that you want to export, then click the "Export" button.
4. Enter the password or the pin for Communicator Certificate DB if the DB is password protected.
5. Then you will be asked for a password to protect data being exported. You may enter one or leave it blank.
6. Re-enter the password to confirm it - If you have chosen one, enter the same password again. Otherwise, click on OK to continue.
7. Select the folder where you want to export your keys to, assign a file name to the key file and save it. Netscape will export the keys as a *.p12 file.
8. Netscape will finish the whole process with a message saying that the export was successful.
B. Importing the certificates into MSIE:
1. Go to your IE browser and choose "Tools" -> "Internet Option".
2. Click the "Content" tab, then click "Certificates".
3. Click on "Import" button to begin the import process.
4. IE will bring up the Certificate Manager Import Wizard. Click Next.
5. Click "Browse" to browse to the folder which contains the *.p12 file and select it.
Note: you may have to change the Files of type to All Files (*.*) to see the p12 file.
6. Click Next.
7. IE will then ask you for the password, which you first entered when exporting the keys out of Netscape. If your keys were not password protected, leave the Password field blank.
8. Check the "Mark the private key as exportable" option if you want to export the keys later on. Click Next.
9. IE will present an option, by default, of automatically selecting the certificate store to store the imported certificate. Accept the default and click Next.
10. Click "Finish" and IE will present a message saying the import is successful.
