Re: Help Please - no access to Web Sites

Hi Jenny

Thanks for you detailed reply below.. After searching round we have found
that quite a few people have suffered this same problem following install of
Cisco VPN software. Problem is that even after you un-install, it leaves
settings in registry, and messes up the IP stack. - not a good end-user
experience at all!!

THe only way we could solve this in the end was a nice clean install of SBS
to get rid of all their settings - costs us some time of course in terms of
restoring everything but we're back in business now.

Thank you for your help

Roger
