Question
Unable to access ASDM on Cisco ASA 5520
I have taken over a network which has an ASA5520. I can access the ASA via ASDM on the maintenance interface but cannot on the inside interface. I can download and install asdm but when I try to connect I get :
"ASDM is unable to read the configuration form the ASA. Please check the configuration and your connection and then try again by clicking the Refresh icon."
I can continue from the error and enter CLI commands to the ASA such as show running-config, etc. Just cannot get the gui up.
ASDM Version 5.0(5)
ASA Version 7.0(5)
Here is my rc:
Result of the command: "show running-config"

Not 100% as been unable to get access to a device to test, but I'm leaning towards webvpn causing issues with asdm access.
If you can get to the cli, try the following commands:
http server enable 65500
then point your browser the https://x.x.x.x:65500 and try the java applet
Actually, yes.... I compared a working version on my network administrator's system and realized that theonly difference between his machine and mine was the Version of Java. I downgraded from 1.6 release 10 and to 1.6 release 7 and I've been fine since. so if executing any upgrades of JRE or the JVM, I'd suggest testing it first or ensuring that you have a roll-back option.

I have seen some problems launching ASDM, I'm never sure of the actual cause, however, and this is an error I have not come across. However, I have been able to resolve the issue by performing a reload and rebooting the ASA. Obviously not the best option without fail over but if you haven't tried that I would recommend it if possible. This has cleared up mysterious issues with ASDM for me each time.
