I did some checking after my last post - I think I might have been wrong on the double \\...

A couple of things:

1) Are you able to use a UNC name?

\\MyServerName\Path\sample.dbc

2) If not, try something like "Data Source=\\10.0.0.10\Share\mydir\sample.dbc";

(not sure if you'll need the "share" or not, and I don't know if you have a subfolder underneath, so you may want to try different combinations)

3) Check out thread 898151 - there was some discussion on this a while back.
