This method throws exception, instead to return true/false

When this method has been called, it throws ComException with the message "The server is not operational." instead to return true/false.
Example:
bool activeServerExists = DirectoryEntry.Exists($"LDAP://{fullDomainName})");

Is this behavior changed after this document has been published?
