We recently changed servers in small office. But we did not touch the Cisco Router other than change the IP address of the DHCP server to the new server. Since then certain laptops that used to work on VPN will no longer connect. We are using Cisco Quick VPN. A couple of laptops can VPN in. The ones that can't get an error message of 5 different possible reasons. The one link that we found on two of the laptops that cannot connect was they are running ESET anti-virus. But we even temporarily disabled eset and it still will not work. Any ideas why this is happening?
