Error The root of the certificate chain is not a trusted root authority Sharepoint 2010

Using Inetmgr I copied the CA’s certificate to a .CER file (C:\rootca.cer.) I then opened Windows PowerShell (as admin) and ran the following commands, each command is one line – sorry about the wrapping:

Add-PSSnapin Microsoft.SharePoint.PowerShell

$rootca = New-Object System.Security.Cryptography.x509Certificates.x509Certificate2(“c:\rootca.cer”)

New-SPTrustedRootAuthority –Name “FC Root CA” –Certificate $rootca
I did an IISRESET and then tested verification again – bingo.
