Assets Pathname error

Immediately after creating a new project on our network (specifically on a PC across a LAN), I always this error reported at the bottom of the Unity screen:

"Assets Pathname couldn't be found"

This started happening after a series of corrupted projects and restarts.

Has anyone seen this error before? Would re-installing Unity help?

Thanks.
