I have an ASA 5520 that has VPN configured on it. I have set up the in the DfltGrpPolicy the DNS and WINS ip addresses. I have experienced on several (4+) occasions where the DNS and WINS just disappears from the configuration. I have a VPNgroup policy that uses the default to get its DNS and WINS. On one occasion the device had mysteriously rebooted by itself and I noticed it missing. The other times it is just missing. I put it back in, Apply the changes and click Save (using the ASDM to configure it). Is this a known issue that is fixed with a new release? Has anyone else experienced this problem?
