Can Webreach access information on a mapped drive?

No, it is not possible

Explanation:
To display the network diagram, Webreach needs to pull out some information from the ud folder, located on the IIS server.

Here is an example of when you try to access a diagram on a mapped drive.

Error reads:

• The diagram does not exist, or you do not have permission to access it

The address bar contains the mapped drive location "Y:" which causes the problem.

The fact that the user cannot use mapped drives with Webreach is actually a limitation of the IIS. Here is Microsoft's explanation:

"When you create or administer a Web site or virtual directory, the option to browse for the physical location where the content is stored for that site or virtual directory includes mapped drives. This may be interpreted as a way to keep the content on a network share accessible through the mapped drive; however, because the nature of drive mappings, this is not a viable option. If you prefer to keep your content on a remote computer, then create the Web site or virtual directory with a universal naming convention (UNC) path to point to the share on the remote computer."

Generally, the problem is that the mapped drives are set on a per-user basis.  The user who has mapped the drive is not the same user (IUSR_<machine>) who is trying to access that drive from Webreach.
