Open File - Security Warning

I pushed out an .exe this morning to all desktops, network wide, and received numerous complaints that when users tried to run the .exe, a popup would prompt for comfirmation before allowing it to run. Its title was:

"Open File - Security Warning"

Of course, there is a checkbox to keep this prompt from reapearing, but we all know how end users can be...
So the 'quick fix' is to create or edit a group policy object and under "User Configuration > Administrative Templates > Windows Components > Attachment Manager", enable "Inclusion list for low file types" and add .exe with the leading period.
After a gpupdate, the security prompt no longer came up.

ASDM error: Unconnected sockets not implemented

Hey everyone, I know it's been a long while since my last post, but I promise to try to make more frequent posts.
One thing I noticed today was that I couldn't launch Cisco's ASDM from my laptop running a clean install of Vista SP1. I noticed the same error on my desktop at work as well, right after login, I'd get this:

ASDM is unable to continue loading. Click OK to exit from ASDM.
Unconnected sockets not implemented.

I was trying to connect to an ASA5505 and an ASA5510, both running 8.0(2) and ASDM 6.0(2). Well after half an hour of research, and not finding a fix, I started troubleshooting on my own. I found the problem to be the Java runtime version I was using. It seems ASDM is incompatible with JRE 6u10. I uninstalled it and installed JRE 6u7 and then ASDM came right up with no errors.
So there you go, if you're running Vista SP1, ASDM will not work with JRE 6u10, try 6u7 instead.

I had a question about where to download JRE6u7, so here it is:
Go to this page, and click the "Download JRE" link, then select your platform and language, and you should be presented with the online and offline installers.
Also, remember to disable automatic updating of your Java engine by going to "Control Panel" > "Java" icon > "Update" tab > and uncheck "Check for updates automatically". The "Java" icon appears in the control panel only when it is in "classic view", both in XP and Vista.
