I have 2 end users where their M:\ drive (personal share folder) multiplies on its own and maps every drive letter available to the personal share filling up My computer with mappings. This will just simply happen the next time you enter MY COMPUTER.. doesn’t need a reboot or re-logon to occur. Everyone uses the same Logon script which maps about 5 different drives. Why would it only happen to 2 users, and when I log off or restart the PC it goes away for the time being.
