I am in the testing phase of deploying Windows 7 throughout my network. We are currently in the process of developing our new AutoCAD 2010 customization and we noticed a very strange thing.
-AutoCAD customized shortcut points to a file located on my L:\2010_MEP\test.arg
-In Windows Explorer, my mapped L:\ drive has a Red X through it, the customized version of AutoCAD fails to load
-When I click on the mapped L:\ drive through Windows Explorer everything appears, the icon for the mapped drive turns green and the customized version of AutoCAD loads up perfectly.
-I have this same configuration for Windows XP machines and it loads without a problem, including when the same mapped network drive is "Disconnected from Network"
-My current login scripts are configured as: net use L: \\wmanas.wmace.com\CAD /persistent:yes for all workstations.
Bottom line: In Windows 7, when a Red X appears, any applications that point to mapped drives will fail to load. When we click on the mapped drives, they "go green" and THEN the applications load without a problem.
I need a solution for this.
