The session setup to the Windows NT or Windows 2000 Domain Controller \\servername for the domain domainname failed because \\servername does not support signing or sealing the Netlogon session. Either upgrade the Domain controller or set the RequireSignOrSeal registry entry on this machine to 0.
To workaround this feature do the following:
1. Use Control Panel to open Local Security Policy in the Administrative Tools.
2. Navigate to Local Policies / Security Options.
3. Double-click Domain Member:Digitally encrypt or sign secure channel data (always).
4. Press Disabled.
5. Press Apply and OK.
