Are u using MD5 or SHA because the higher the encryption the more over
head you will have.

Yes I have looked at that and the client says it is just to much work.

Elijah,
Just in case you haven't read this, here's what I found...

Dec 19, 2002, 6:03am PST
Not sure if you still have a problem, but... 

Have you tried to changing the Outlook Client so that it does NOT use
the Logon Network Security? (To check this, Right click the Outlook Icon
and go to properties- Select the MS Exchange server and click the
properties button. Then select the Advanced tab, and set the Logon
Network Security to NONE.) This will prompt the Outlook client to
provide the NT domain authentication info - username; domain; password -
rather than trying to take it from the OS. 

I had this same problem and this is what I did to resolve it. There may
be a more elegant solution, but I am unaware of it. 

Hope this helps... cholmes@xxxxxxxxxxx

All,

I need some serious help for a serious problem. We have implemented a
vpn solution with 2 3030 concentrators. All work fine except for the
dialin users, everything is terribly slow I used dialin tonight and had
a 50.6 connection and it was creeping along like it was 9600 baud. I was
getting dns resolution problems on web pages I knew were up like CCO. I
have enabled LZS compression on both concentrators. I also have users
complaining that they get exchange errors like can't contact server.
Here is the confusing and tricky part. Now on the other hand broadband
users just couldn't be happier. I have broadband at home also and all
this crap I experienced tonight on dialup none of it has shown it's ugly
head on broadband, no exchange error or anything. I have looked over CCO
and looks like there was a few bugs for the vpn client but supposedly
fixed and I am using the latest client. Also on the Network Professional
news group on CCO there are just a TON of people complaining about VPN
and outlook access in some form or another with no resolution. 


I called TAC and opened a case and the TAC engineer said yeah he knows
about the errors and that is the nature of the VPN beast and said Cisco
likes to recommend to custmers implementing VPN technology that they put
a OWA(outlook Web Access) server in a dmz some place because web
browsing is a much better experience over VPN. I just can't accept this
as an answer I am out of ideas of what to try and there has to be
someone out there in this big IT world that has happy dialup users using
Outlook/Exchange through vpn concentrators. I did follow the
recommendations on CCO about lowering the MTU settings on the client
side but that does not fix it.

If anyone has seen this and have a fix please let me know it would be
greatly appreciated. Out of all honesty I am looking for any experience
at all just to here what the general consensus is on this, so if you
have a fix or not I would like to here about your overall experience.

Thank You
