After Hibernation Mounting Of Network Share Not Possible Anymore

Hello,

after hibernation/standby it is not possible anymore to get access to mounted network shares. Only a reboot helps in Windows 7 to get access to the mounted network shares again. It only appeared after installation of BitDefender Internet Security Suite 2016.

Has anyone a solution for it, when coming back from hibernation that the network shares are available again?

Thanks in advance.
