Well it seems the current update to java (6 update 10) does not work with Cisco ASDM. After the update trying to connect to a Cisco ASA will give the following error: “Unconnected sockets not implemented”. CLI still works of course but if you use ASDM don’t upgrade past JRE 6 update 7. You can get older java versions here.
My config: Vista Ult x64 – JRE 6 u10 – Cisco ASDM 6.1(5) (most current ASDM as of now)
What I had to do to access ASDM after the java 6 update 10 “upgrade”.
1) Remove ASDM* (ASDM installer seems to look for java so this must be done before removing java)
2) Remove Java 6 update 10
(I rebooted here)
3) Install Java 6 update 7* (I ended up running both the 32bit and x64 installs. I think because ASDM is 32bit and didn’t see the 64bit Java install?)
4) Re-Install ASDM
*Note: It may not be required that your remove ASDM on a 32bit system or if you install the 32bit java 6 update 7 as ASDM may just see the new (older) java install. When I installed the 64bit java this is what I had to do.
Best of Luck and I hope this helps someone out.
