I am running AutoCAD MEP 2012. I am unable to open drawings that are stored on a network drive. I continue to get a "Unhandled Access Violation Reading 0X0000 Exception at f5bfaad0h" and AutoCAD closes. If I copy that same file to the computer and make it local, it opens without any problem. All files local open just fine. Also, I am able to open the same drawing on the network from multiple other computers.
I have tried to repair AutoCAD and check all network settings on the computer, but everything appears correct. Any suggestions on the issue?

Describe this location in more details other than "network": and confirm you do have read-write access to it through your Windows Log-in rights (AutoCAD does not override these ever).
Yes, I can confirm that I have Full Control of the Drawing(Read/Write Control). The Drawings are stored on a Drive in the server, which is shared to all Users. All Users have Full Control over all Drawings on this Drive, there are no permissions in place for any User accessing anything within this Drive.
The only thing that has changed is upgrading from AutoCAD 2010 to AutoCAD 2012. The AutoCAD 2010 products have been completley uninstalled and removed. Then the AutoCAD 2012 was installed. NO Profiles have been imported - the 2012 is running the default profile. When I try to open a drawing from the Drive stored in the Server, I get the Unhandled Violation message. If I copy that same drawing to my computer it opens and works just fine. I have already tried to repair the AutoCAD installation, but that didn't help.
There are 100+ other users that have gone through the same steps as far as the Upgrade process and how the Drawings are being open and have no problems what so ever.
What is your server OS? - Server 2008 R2
What is your desktop OS? - Windows 7 Pro SP1 64BIT
Basically, what changed recently? - The only thing that has changed is the install of AutoCAD 2012.
Since it is only your computer, it could be something as simple as a .NET Framework issue. The only thing that changed was installing an upgrade to AutoCAD, which also installs an upgrade to .NET as a prerequisite. You might consider removing old versions of .NET and making sure your .NET 4 is up-to-date.
Other than that, see if there is an update to your network NIC driver.
.NET Framework issues can be resolved using the .NET Framework Cleanup Tool. More information about this tool can be found at my discussion thread here:
