Slave starts -> Mapped Drive vanishes

Hello All. I have a Problem with a Deadline render node. As soon as i start the deadline slave process on this PC, my mapped drive (where all my project files, repository and assets are stored) gets removed and is no longer accessible for this render node. The only way to access it again, is to shut down deadline slave process and remap it.

I have another PC (render node) that is 99% the same as the one with the problem but this one works. This clearly shows that the problem must be related to my PC settings and not deadline, but i have absolutely no idea where i would need to look to fix this, thats why im posting here.

PC Specs:
CPU: 2x intel xeon e5-2696v3 (36C/72T)
GPU: 1x Gtx Titan Black 6GB
GPU: 1x Gtx Titan classic 6GB
RAM: 64 GB DDR4 ECC
Mobo: Asus Z10PE-D16
OS: Windows 7 Pro 64bit

No one any idea? I still couldnt fix it myself.

Fixed it by completely removing Deadline from all machines and reinstalling it.
