SSLCertHash through ADSI in C#

I am trying to set the SSLCertHash property to the byte array that contains
the SSL certificate's thumbnail with following code:

string path = "IIS://localhost/W3SVC/" + webSiteNumber;
DirectoryEntry site = new DirectoryEntry(path);

X509Certificate2 sslCertificate =
Utility. GetSSLCertificate(distinguishedSubjectNa
me, true);

string thumbPrintInHex = sslCertificate.Thumbprint;
byte[] thumbPrintBytes =
Utility.ToByteArray(thumbPrintInHex);

site.Properties["SSLStoreName"].Value = "MY";
site.Properties["SSLCertHash"].Value = new
byte[thumbPrintBytes.Length];

The last line (that sets the SSLCertHash property value) throws {"Exception
from HRESULT: 0x8000500C"}. Any help is appreciated.

Thanks.
