Hi everyone,

Just picked up a new Cisco ASA 5520 this morning. Been messing with it all day. Just got the software updated to 8.0(4). This ASA did not have the ASDM loaded, I loaded 6.1(5). All seems to be working fine till I try to access the ASDM either by web or the win32 app. I am receiving the the following errors each time I try to bring it up:

ADSM is unable to continue loading. Unconnected sockets not implemented

I have downgraded to 6.0(2) in hopes this may correct the issue, no luck still not able to access it. I am going to try to downgrading the image file to 8.0(2) but I dont think this is going to correct it, I am hoping someone here may have an answer. Here is the current system info:

Cisco Adaptive Security Appliance Software Version 8.0(4)
Device Manager Version 6.0(2)

I ran into this one myself.  The fix for me was to uninstall ASDM from add/remove programs, then delete the .asdm folder from my windows local profile.  Updated Java to latest version, rebooted, and then reinstalled ASDM from the firewall.

No idea how it started, though.  I can confirm that this is an ASDM issue only, changing the ASA image won't do a thing.  I was able to confirm this by pulling up the ASDM from other computers that didn't have any version of the ASDM installed on it already.

I tried the uninstalling, I even reloaded my winows box from an image to get a clean start, stil the issue remains. Now I am wondering if its jave itself. I am gonna try to uninstall and grab an earlier version see what happens.

Ok you have seemed to put me on the right track, this is a Java issue, now the question is, is there specific version of Java that should be installed? I was using version 6 update 10 with failure

I'm currently running 1.6.0_07.  I think I was on update 10 WITH failure.

This sounds much like the problem I am having with my machine. However the machine I need to have JAVA installed on does not have an active internet connection to it. Does anyone know how to get a stand alone installer of the JRE?
