Drive Mapping Issue

Offlining and re-linking won't purge the saved-up references to those other paths, within that same project. 

Recreating the template projects with known-correct paths, sounds like the safest approach.

So to clarify, could I offline and relink everything in the project using the proper drive letter (in this case, P) and then it won't revert back to the IP address after that assuming everyone who tries to open it thereafter has the same server mapped to the letter P? OR, are you saying it doesn't matter if you relink it, what matters is how it was initially imported? Wondering if I'd have to recreate this template projects from scratch, reimporting everything now that the server is mapped to P or can I simply offline and relink instead? Thanks for your help!

Having the same issue! Any solutions?

If it imported any clips before the drive was mapped to Z or whatever, it will maintain the original links. Remember, all parts of a project are merely text metadata about what assets are involved, where they are located, what sequences you've created et al.

To fix this, you would need to offline the files on each computer, then locate to the mapped drive.

Having the same issue. I got all of my editors to map the server to the same drive letter so we won't have relinking issues and yet Premiere still considers the IP address for some but not all of our footage. Does anyone know how it determines this?
