Recently I've installed cisco vpn client 4.6 to connect to a customers site for remote support. I'm using Windows XP.
I have a very strange side effect (which costs me 2 full days untill now...).
When I startup my computer, I can do everything on the internet (e.g. all ports, web, mail, rdp, news, etc, active sync to mobile device, network browsing)
After 5 minutes however, I cannot go outsite to websites anymore and I cannot do active sync and ports 138, 139 (a share to my machine doesn't work anymore). Other things like port 3389 (rdp) are going well.
BUT, when i FIRE up the connection ONCE through the customer through the VPN client and DISCONNECT immediately, everything works fine afterwards.
I tried to remove the VPN client but then repeatly every 5 minutes after boot, the webbrowsing and activesync and network shares are "dead".
Is it a firewall thing? Are there some "hidden" rules? Why can I ping to an outsite site (ping
Kind regards and thanks for any help
