Retrieving Certificate Information from Windows Server 2008

With "issued certificates" do you mean certificates issued by this field, or by this box?

Anyway, something like this should get you started playing with the certificate stores:

using System;
using System.Security.Cryptography.X509Certificates;

class CertificateStoreSample
{
    static void Main(string[] args)
    {
        X509Store store = new X509Store(StoreName.Root);

        store.Open(OpenFlags.ReadOnly);

        foreach (X509Certificate certificate in store.Certificates)
        {
            Console.WriteLine(certificate.Subject);
        }

        store.Close();
    }
}
