first tftp an asdm image to the asa (looks like you already did that)

then run the following commands

http server enable
http inside
asdm image flash:/asdm-641.bin

that should enable any clients from inside network to have access to ASDM configuration

btw, i'd make the inside IP static for one.  so when you go to it doesn't come up with anything?

that did not work.

i can ping the
i did a port scan and it is up, and it can see port 443

i did a wireshark capture and i am getting a "Handshake failure"

that's odd.  handshake denotes its failing during SSL negotiation. perhaps client doesn't like options it has with what the asa is offering

try the following or attempt a different browser (what are you using anyway?)

ssl encryption aes256-sha1

i get this error:

The 3DES/AES algorithms require a VPN-3DES-AES activation key.

hmmm.  because what I'm thinking is going on here is that single des is used for the cert and the client is rejecting it due to its insecure nature thus a handshake can't be formed since the asa can't do any of the options the client will accept.

which browser are you running?  we may need to lower the browser security to allow it to communicate to the asa
