We have two VPN concentrators, one running vpn3005-3.0.1.Rel-3des.bin and the other running vpn3005-4.1.7.F-k9.bin. The VPN concentrator with the latter firmware loses its admin password every few months, although most, if not all, of the configuration remains intact (not always). This sounds to me like a hardware problem, but I thought someone else might have another idea given we don't have Smartnet currently. Thanks
For VPN 3000 Series Concentrator, Federal Information Processing Standards Publication (FIPS) release 3.1.X, be aware that there is no way to recover your system if you forget the Administrator password. Take appropriate measures to safeguard your password. If you forget the Administrator password, you cannot log in to your system, and you have to return the VPN Concentrator to be recovered.
