Solved!!!
First - add your untrusted certificate to Personal Certificates
Verify that the server certificate was properly installed by performing the following steps.
Click Start, click Run, type mmc in the Open text box, and click OK.
In the Console1 window, click the File menu and then click Add/Remove Snap-in.
In the Add/Remove Snap-in dialog box, click Add.
In the Add Standalone Snap-in dialog box, select Certificates and click Add.
On the Certificates snap-in page, select Computer account and click Next.
On the Select Computer page, select Local computer and click Finish.
In the Add Standalone Snap-in dialog box, click Close.
In the Add/Remove Snap-in dialog box, click OK.
In the console tree, expand the Certificates (Local Computer) node, expand Personal, click Certificates, and double-click the new server certificate. On the General tab, there should be a note that says You have a private key that corresponds to this certificate. On the Certification Path tab, you should see a hierarchical relationship between your certificate and the certification authority (CA), and a note that says This certificate is OK.
Close the Console1 window. Save the console settings with a descriptive name, such as LocalComputerCertificates.msc.
Second:
Start LocalComputerCertificates.msc
Add your untrusted certificate to \Trusted Root Certification Authorities\Certificates
Profit!!!
