Hi,

i have a 5510 and the asdm was working fine all the time. But the there was a power outage and ups ran out etc. On boot, internet works but asdm cannot be accessed and also remote access vpn does not work anymore. When i cli to it , i see all the settings correct and intact.

My java version on my client is

C:\>java -version
java version "1.6.0_19"
Java(TM) SE Runtime Environment (build 1.6.0_19-b04)
Java HotSpot(TM) Client VM (build 16.2-b04, mixed mode, sharing)

There was an asdm-508.bin also which was removed but it was not set as the image to use. I get the error below when trying to access it local or from outside
