NBT-NS Poisoning and Exploitation with Responder - Lab Problems

Hello all,

I have already tried many things, but I have problems in the Lab “NBT-NS Poisoning and Exploitation with Responder”.

For me simply the exploit does not work, I copy the Powershell command down but it does not work.
I also found this post: Lab 11 but it didn’t help me either.

Thanks a lot!
