In this case, to support Samba, you want the value to change from the default of 3 to 1.
The key was missing, so I created it first (DWORD).
Tried values - 1, 0, 2, 3 (in this order). No luck.
Funny thing is, when account has password but I leave it in Mede8er blank, I can see the shares BUT can not access them.
When I try to access them, Mede8er will ask password once again and then if I enter correct password shares are accessible. Very weird.
More ideas what to try?
