AutoCAD 2010/2011/2012 DWG Format

[#1]

When I try and open a file from the network that another user already has open, I receive the following message:

"Cannot find the specified drawing file. Please verify that the network drive is available and the file exists".

This happens when using Novell Netware. Is there a resolution?

[#2]

It has been reported that the following will resolve this:

In the Novell Client Properties, Set 'File Caching' and 'File Commit' to ON. You should then be able to open the files.

[#3]

I am receiving this error whether I am attempting to view a drawing file via the network, via a lotus notes database, or loaded locally.:

"Cannot find the specified drawing file.  Please verify that the file exist"

The Autodesk product I am using is Autodesk 2012 LT (trial)

The operating system is Widows 7 (64 bit)

I have had the same error for multiple Autodesk readers aswell on this same PC including:

Design Review 2013, 2012, 2011

True view 2013, 2012

I have administrative rights to the profile in question and I have also attempted to use a separate profile but received the same results. All attempts to manually set the file association have liekwise failed.  the program will initialize, but the error message returns with no ability to veiw the drawing file(s).

I have also removed/uninstalled all of the above mentioned programs via Autodesk instructions/procedures for proper removal of folders/subfolders/registry entries (HKey local machine and current user) as well as stoping any autodesk program running in task manager.

My next step is to re-image the machine to make the file association stick to an autocad program. 

Please help.
