Do you need/use IPsec?
As a temporary workaround you could try disabling the IPsec service and
rebooting.
Go to services.msc locate IPsec Services and set startup type to
disabled.
If one of the updates has broken something then it might be a time
consuming
job to identify the one causing this
I think error 1747 is kinda generic and can be covered by a multitude of
reasons unfortunately.
What do the eventvwr logs tell you?
Perhaps the ipsec group can shed some light

I've installed all the critical updates after installing a clean
install
from the slipstreamed SP2 XP pro disc,
KB873333, KB873339, KB883939, KB885250 , KB885835, KB885836, KB886185,
KB887472, KB887742, KB888113, KB888302, KB890046, KB890175, KB890859,
KB891781, KB893066, KB893086, KB893803v2, KB896358, KB896422, KB896428
These are the 21updates I've downloaded. I forgot which one was the nat
if
there was.
:
What updates are you installing? Is there by chance a NATT one getting
installed?
Let see if the IPsec group works better.

Its happening now an all my machines, all I do is install updates
then
it
get currepted & never start again, on WIndows XP SP2 preinstalled &
windows
2000 SP4!
I installed Sygate firewall on one machine after formating thinking
it
was
some sort of IPsec vulnrability, still didnt help. keeps getting
currept
after updating:\
am going mad over this 5pcs now all with the same thing two of them
use
wirless & depend on IPsec
Ill post this in the IPsec group, thanks for the notice
--
Give me my Exchange copy plz:\
:
There is now an IPsec newsgroup at
microsoft.public.windows.networking.ipsec
that should be a better place to post.
When did this start happening? After installing/upgrading
something?
You
mention a firewall, was everyhting working prior to firewall being
installed?

Hi, I''m using WIndows XP pro SP2 Build 2600 05031-1519
I've got this weird problem with IPsec service. it wont start at
all
giving
me "error 1747: The Authentication service is unknown"
My system can only connect to the net by manual setting, can no
longer
optain IP via DHCP,
It keeps happening even after I format & on both my pc's after I
connect
to
the net!
First thing I did install a firewall offline then connect & did
all
neccessery updates & still get this!
any clue on how to fix it? is this a virus spreading? I've got PC
cillin
reporting nothing at all!
TY
