Write Adobe Lightroom catalogs to a network share

To work around the restriction of Adobe Lightroom refusing to write catalogs on a network share (for Windows PC);

• Connect the share as a normal network share on the Windows PC; for example drive letter Z:
• Create the desired directory on the share; for example Z:\Lightroom
• in a command promtp run subst x: z:\lightroom (or any free drive letter)
• Now you can create a new catalog on X:

The command subst x: z:\lightroom can be made as a shortcut, or even set up as a logon script in the start menu for all or single users.
