Unhandled exception on domain network only

P: n/a
Hello,

I may have posted in the wrong place, if so, feel free to move my post (just
notify me where you put it via email or something)

I’m having a problem with my program that I cant readily explain. The
program connects to, then reads and creates a new flat old Dbase files (.DBF)
stored on a network drive. The program itself is run from the very same
network drive/folder.

When I run the program over a WORKGROUPed network, it has no problems. When
I try to execute the program in a DOMAIN network, it crashes with an
unhandled exception error found at the bottom of this post.

I have pasted below the code that appears to be generating the error.

I have check the NTFS and share permissions of all files and folders
involved, and everything looks right. I even tried giving “everyone” full
permissions- no help.

QUESTION:
Other than permissions- what would cause a program to generate unhandled
exceptions on a DOMAIN network, but not an a WORKGROUP network?
I don’t know if I will be able to install visual studio debugger on the
domain network to step through the program. What other suggestions would you
have for debugging this (both at home, where I have the visual studio AND on
the domain where I do not)?

Many thanks for your help,
Oliver

CODE:
Dim DBConn
DBConn = OpenDBFConn(".\\") 'specify the current folder

Dim create_string = "SELECT [CTtemp#DBF].*, [SYSPROF1#DBF].SYSCOMP AS cocode "
create_string += "INTO [" + Dest_File_Name + "#dbf] FROM
[CTtemp#DBF], [SYSPROF1#DBF] "
create_string += "WHERE ((([SYSPROF1#DBF].SYSCOMP)='" +
CompanyCode + "'));"

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.
