An attempt was made to access a resource in a foreign domain by using the Kerberos protocol. The only domain controller that was available for the domain was a Microsoft® Windows NT® 4.0 domain controller, which does not support Kerberos. A connection could not be established.

Sample Event:

No suitable Domain Controller is available for domain %1. An NT4 or older domain controller is available but it cannot be used for authentication purposes in the Windows 2000 or newer domain that this computer is a member of. The following error occurred:%n%2

Attempt the request again, allowing NTLM authentication, or ensure that a Microsoft® Windows® 2000 or later domain controller is available.
