While it might be a nightmare, this is just a standard windows security protection and also faced by users that do not use VMware products.
Mapped drives (eg. UNC shares that are mapped to a disk drive) are limited to the user that maps them.
HuanguoZhong actually already pointed to the workaround let me try an easier to read alternative.
TL;DR you have to make a registry change if you want to disable this security protection.
edit: Oh and if the above registry editing does not work (for whatever reason) you could possibly use the net use syntax from above to map your share to a different drive from an admin command prompt.
