I have been having ongoing issues with CIFS shares in the VPN portal on ASA5510 8.0(4). Every few weeks, CIFS shares stop working through the portal. When it stops working, you get an "Error contacting host" right after you enter your Windows domain credentials. I replaced my hostname with the ip address to rule out name resolution as the source of the issue. I have found no less than 3 Bug ids associated with this issue: CSCsl94183, CSCsk29306, CSCsq73588. At this point, the only thing I can do is reboot. This is not a good work around for me since I have to fill out outage notifications every time I bounce a device. I am running 8.0(4). I don't think the issue is resolved. It's still happening to me. Is anyone else having this issue still with 8.0(4) code?
I have this problem too.
