Event ID: 4294 Source: IPSec
The IPSec driver has entered Secure mode. IPSec policies, if they have been configured, are now being applied to this computer.
|English: Request a translation of the event description in plain English.|
The IPSec Driver (%SystemDirectory%\drivers\ipsec.sys) is loaded at system startup, regardless of the startup setting for the IPSEC Service (PolicyAgent). The Driver has an OperationMode registry entry (REG_DWORD) under HKLM\SYSTEM\CurrentControlSet\Services\IPSec, which determines how the driver will function until/if the IPSEC Service starts. One of three System events will be logged almost a minute after EventLog's 6009 startup event, depending on the OperationMode setting and startup type for the IPSEC Service. Here's the driver registry settings and resulting System events:
OperationMode 0- Permit(Bypass). Causes Event 4295.
OperationMode 1- Block. Causes Event 4296.
OperationMode 2- (Reserved). Causes Event 4295.
OperationMode 3- Stateful. Causes Event 4297.
Event 4294 will occur once the IPSEC Service starts, about 8 seconds after the event for the Driver if the Service's startup type is Automatic.
Event 4295 (Bypass) will occur if the Service is Disabled, regardless of the OperationMode registry setting.

When you try to open the Internet Protocol security (IPSec) Microsoft Management Console (MMC) policy on a Microsoft Windows Server 2003-based computer this event might be logged. A corrupted file in the policy store can cause this problem. An interruption that occurs when the policy is being written to the disk may cause the corruption. See ME870910 for more information about this situation.
See ME555281 for information on how to create offline L2TP/IPSec certificates.
