file_system, IPSec services cannot start

1. IPSEC PolicyAgent Service: Ipsec Driver failed to start.

2. Cannot start IPSEC Services

Hello -

I'm getting a strange error when I attempt to start the IPSEC Services 
service.
Here is the Event Viewer application entry:

The IPSEC Services service terminated with the following error: 
An invalid argument was supplied. 

When I try to start it manually from services.msc - I get the following 
dialog message:

Could not start the IPSEC Services service on Local Computer.
Error 10022: An invalid argument was supplied.

I have SP2 installed and am attempting to run Linksys QuickVPN.

Any help would be greatly appreciated.

TIA,
RV

This affects MS SSO from starting which in turn affects BizTalk from running 
correctly.

6. IPSEC Services Not Starting...

I've been successfully running a Small Business Server 2003 with 25 Clients. 
I recently updated the Trend Micro SMB product to their latest Worry Free 
solution. It ran fine for a few days, then MS submitted updates that required 
the server to restart. I came in the next morning to find the entire network 
down, everybody going crazy because they couldn't work, etc.

What had happened was that the new version of Trend-Micro provides & 
installs some sort of a Firewall service, even if it's told not to.... 

The problem was that the IPSEC services would not start because a required 
port was being used by another program or service.

I did not have time to mess around, un-installed trend micro, re-booted and 
all is up and running now. I left the mail scan portion of trend micro on the 
system, which works.

I would like to re-install the trend micro product, but how would i prevent 
these types of issues from re-ocurring? I do not have a backup server, nor a 
test environment to mess around in, do not want to experiment on the 
production server. Any suggestions would be appreciated. Thanks!

8. IPSec Service failing to start due to DNS update

Is this is serious a problem as I suspect?

I have been configuring and testing a new server for a client and ran 
into this problem a couple of times. Basically, a recent DNS update to 
counter spoofing attacks can result in the DNS service occupying some 
ports that the IPSec service uses, which results in the IPSec service 
failing and all network access to the box being blocked, i.e. no remote 
access to fix it.

The fix seems to be to remove the registry entry MaxUserPort. Should we 
all be rolling this out before the next reboot potentially causes a lot 
of preventable site visits?
