USB mass data drive, flash drives


  • On SBS2011 can you block access to USB ports to stop users downloading company data to flash drives etc on client computers, by a group policy edit?

    Can you also set it so a admin logon can temporarily allow this use?

  • Hi Charles,
    We can block access to USB drives in group policy, the path to the policy setting is:
    Configuration > Policies > Administrative Templates > System > Removable Storage Access
    There are several policies you can configure there, if you just want to stop users from writing data to USB drives, then you can configure "Removable Disks:  Deny write access." You can also disable read access as well.
    If you want to exclude admin from this GPO, you can organized your non-admin users in one security group, then change the scope of the policies:

  • You can do it through Group policy 

    1) Create GPO or edit your current GPO- Goto  User configuration –> Policy –> Administrative template –> System –> Removable storage Access and Enable deny Read/Write Access.

    You can configure register to block USB's,

    2) Create GPO or edit your current GPO - Goto User configuration –> Policy –> Administrative template --> Registry -->New registry item -->

    Then save it.
