ASA5520 loses its DNS for VPN

[bkootstra]

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?

Does Cisco has an answer to this issue?

Thanks for listening.

Brian.

In the same group policy where you have the split tunnel networks configured, specify the domains that you want to be resolved via the secured networks using the "split-dns" command.
