What setting to make the network shared drive mapped for user login
I have 2 users, userA and userB, here is what I saw if the users login to the same pc one at at time:
UserA login:
4 GPOs applied under Computer policy
No user policy is applied as it said the loop back process policy is enabled for user configuration policy.
Shared drive X mapped.
UserB login:
Same 4 GPOs applied under Computer policy
1 user policy is applied.
Shared Drive Y mapped.
I am trying to figure out what GPO effect the shared drive mapping, I checked all 4 GPOs one by one, there is NOT any logins scripts attached, or GPP for network drive, as I mentioned earlier, the AD user profile does NOT specify any login script neither, so I am wondering if any else way I can make the network drive mapped with windows user login?
PS: There is NOT any batch file in user startup folder.
There is .bat file for login mapping at domain level, however no idea how it is attached.
Much appreciated for any ideas
