I have this strange issue and it ONLY happens on wifi.
If I browse to windows share: \\hpdsfandp\common$\folder1\folder2 - within seconds explorer changes the directory back to \\hpdsfandp\common$
*this does not happen if I'm on ethernet
*this does not happen if I go to a different server (eg) \\etdb2\c$\folder1
I tried diff wireless access points and it happens on both. Sometimes the issue goes away but then comes back the next day
I did run wireshark on the client and I got a few errors:
ERROR (SMB): NT Status: STATUS_INVALID_HANDLE
ERROR (SMB): NT Status: STATUS_OBJECT_NAME_NOT_FOUND
