FIX: Error message when you try to log on to a domain by using Kerberos authentication on a Windows CE 6.0-based device: "KDC_ERR_S_PRINCIPAL_UNKNOWN: Server not found in Kerberos database"

In Microsoft Windows Embedded CE 6.0, you use the Kerberos authentication service on a fresh device or on a device on which all the certificates have been deleted. When you try to log on by entering a user name, a password, and a domain name, the Kerberos authentication may fail. You also see the following error message during the network trace:
KDC_ERR_S_PRINCIPAL_UNKNOWN: Server not found in Kerberos database.
This problem occurs because the domain name was not converted to the fully qualified domain name (FQDN) when the string filled in the form of the domain name. The Lightweight Directory Access Protocol (LDAP) in Windows CE passes the FQDN or the NetBIOS Service Principal Name (SPN) to the Kerberos Security Support Provider Interface (SSPI).
