We upgraded our Windows 2000 AD,DNS,DHCP to 2008 R2. We use a Cisco ASA to VPN to network for our salesmen. Everything had been working fine.
Yesterday I test a single user VPN connection to network and worked fine. But no other users can VPN in except the single user.
All users are in same AD OU, all use same Cisco ASA VPN client.
I did have to make changes on ASA to modify VPN group settings for servers to new server ip addresses.
I see Kerberos ticket request for each different user, but still only one can connect.
