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.

EDIT 2008/11/26@08.14

I had a question about where to download JRE6u7, so here it is:

http://java.sun.com/products/archive/j2se/6u7/index.html

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.

Weekend update...

Hey everyone, I just got back from a week-long trip to Charlotte, NC, where I attended Microsoft course 2274C, on managing Windows Server 2003. So the first few days, I didn't really learn anything I didn't already know, but Thursday and Friday, I picked up on some neat things I knew Group Policies could do, but never got around to play with. So the security side of the training was great. It all took place at McKesson's "Paragon Headquarters" on the north side of Charlotte, which was great, because I spent just about every evening in Concord Mills, and spent some time at the Lowe's Motor Speedway.
Anyway, here's some pics.

HOW-TO: Backup/Export Exchange Mailbox data from Outlook

When I changed jobs last year, I remember having to backup my data file from within Outlook using this freeware tool from Microsoft. However, now in my new job, we use Exchange whereas before, we used IPSwitch Imail with POP3 access enabled for mail clients.
So here's the problem:

(direct quote from the download site)
Note: Personal Folders Backup only backs up .PST files. If you have a Microsoft Exchange Server mailbox, your server mailbox folders are likely backed up regularly by your server administrator.

So to make things easy, here's a how-to for exporting all your data from your exchange mailbox to a regular .PST file which you can later import back into Outlook to access as an archive. The full-res pictures are here.

1. Within your Outlook client, click "File"->"Import and Export"















2. Select "Export to a file" and click "Next"















3. Select "Personal Folder File (.pst)" and click "Next"















4. Select the top-level of you Exchange Mailbox and check "Include subfolders" then click "Next"















5. Type the path and filename for the file to be created and click "Next"















6.Enter a name to be displayed when you add the backup .PST file to the Outlook client. Also, enter a password if you want to protect the file from unauthorized access. Click "OK"















7. Re-enter the password for the system to begin file creation and click "OK"








After this screen, the .PST creation begins. This took about 20 minutes on my mailbox, which was almost 1GB of data.
When the process finishes, you can now copy the newly created .PST file to a CD, DVD, etc. somewhere safe.
