Thought I read somewhere on the MS sight that the Cisco
VPN didn't work with SP2. I've put SP2 on both XP
computers at home and cannot connect now. No, no, it's
not the XP firewall. First thing I did was turn that
off.

I read this was a known issue and that there is a
hotfix. I can't find it in the KB. Anyone know how I
get it?
 
Is this an L2TP ipsec VPN using Nat-t? I have teh same issue - 818043 fixed
this in Sp1 but you cannot apply the fix to Sp2.

Ewww, Mark, turn that firewall back on !

Wild guess: Turn off the built-in firewall in Cisco's vpn client (which in
fact is a barebone zonealarm jobbie)
Also, cisco's vpn client will prolly be running across port 500. you might
want to try and make an exception in the icf for that port (on udp)
But that's me guessing...:)

Leo,

Thanks for the input but I can't configure the Cisco VPN
at all. It's a client's VPN package and the only
settings are user name and password. Win XP's firewall
is off, and my Zone A is off. The only firewall is my
Netgear wireless router which has never given any problem
before I installed SP2, and has nothing in the log that
shows it has blocked anything.

I swear I read there was a known problem with a hotfix,
and now I can't find it.
 
As i said previously, the 818043 fix that is suppsed to be in Sp2 IS NOT IN
IT - L2TP VPN's do not work in WinXP SP2 when using Nat-t

Simple, straight forward, error by Microsoft which i'm still trying to get
them to admit.

loads of people have this problem - i have a support incident open with MS
at the moment.

Per my email to you: The 818043 patch is in XP SP2. If you are using
a MS L2TP VPN Server that is running Windows 2003 Server, then you
have the NAT Traversal capability. My office of 40 employees use this
nightly now. Note that there may be compatibility when trying to
connect to other IPSEC-based VPN servers (Cisco, in your example).

Note that you should be able to file a free support incident with MS
since SP2 damaged the ability to do NAT-T with third party providers
(SP-2 specific issues are generally free).
