Hello. Within the last days, I have been getting lots of calls about my users trying to connect using the Cisco VPN client. They are able to enter their username and PIN, but then it just goes to "not connected", no errors. If they just keep trying, they connect eventually. They are all using version 4.0.5 and hitting our 3000 concentrator. The security is handled by our RSA SecureID server. there have been no changes to the 3000 or the security server. Any thoughts?
