Hi i have a new 5505 and i have done a few configurations on it. When i try to reset it to the factory settings via asdm i get an error saying it could not be done. I have used config-factory-default using the cli option available in the asdm. I am using asa 8.2 and asdm 6.2. Will erasing the flash reset to factory defaults.

Yes, that will clear all the config and set it with no configuration.

Please console into the ASA and configure the inside interface IP Address as well as the DHCP server.

Here is the configuration for your reference:

interface vlan 1

     nameif inside

     ip address 192.168.0.1 255.255.255.0

dhcpd address 192.168.0.11-192.168.0.250 inside

dhcpd lease 3600

dhcpd enable inside

Also please ensure that you did "no shut" on the interface where you connect your PC to.

You can perform the following:

clear config all

wr mem

The above will clear all the running configuration back to default, and "wr mem" will save the cleared running config to memory.

Hope that helps.

after performing these 2 steps

clear config all

wr mem

now i have lost access to my asa. the asa has been previously configured as dhcp server for inside interface. now its not issuing an ip address to my pc. i have tried pinging it and tried connecting via asdm and it doesnt seem to respond. it tried setting my pc to be in the 192.168.1.0  range and it doesnt respond. any suggestions
