Re: IPSEC Goes Into Block Mode After Driver Update

Maybe due to installing MS08-037? See the latest SBS team blog.

SBS 2003 SP2 Premium (2 NIC). I updated the Promise TX 2300 BIOS and
Windows driver to the latest versions and rebooted the server. When server
restarted I got a 'At least one driver...' error message. There was no
network. I checked services and discovered that IPSEC was not started.
When I tried to start it I got:

Event Type: Error
Event Source: IPSec
Event Category: None
Event ID: 4292
Date: 25/07/2008
Time: 12:06:38 PM
User: N/A
Computer: GLIDDEN-SBS2K3
The IPSec driver has entered Block mode. IPSec will discard all inbound
and outbound TCP/IP network traffic that is not permitted by boot-time
IPSec Policy exemptions. User Action: To restore full unsecured TCP/IP
connectivity, disable the IPSec services, and then restart the computer.
For detailed troubleshooting information, review the events in the
Security event log.

So I disabled IPSEC and rebooted the server. Got the network back and was
then able to enable and start IPSEC.

What was this all about?
