| Event Id | 3227 |
| Source | NETLOGON |
| Description | The session setup to the Windows NT or Windows 2000 domain controller \\Server for the domain Domainname failed because \\Server 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. |
| Event Information | According to Microsoft: CAUSE: This behavior occurs because the Windows XP-based client tries to sign or seal the secure channel. Windows XP Professional does this by default. However, Windows NT 4.0 is not configured to do this by default. RESOLUTION: To resolve this issue: 1. Click Start, and then click Control Panel. 2. If you are using Classic view in Control Panel, double-click Administrative Tools, and then double-click Local Security Policy. If you are using Category view in Control Panel, click Performance and Maintenance, click Administrative Tools, and then double-click Local Security Policy. 3. Under the Local Policies\Security Options node, double-click the Domain Member:Digitally encrypt or sign secure channel data (always) policy to open it. 4. Click Disabled, and then click OK. |
