Wonder if the community at large can help.
I have 2 kali linux instances running on Virtual Box and both up to date. On the challenge Script Kiddie, I can perform the exploit perfectly and recieve a reverse shell in seconds on computer A. On computer B, no chance. It sits loading and never catches a shell despite repeating the process several times and following the exact same steps. they are on the same network, and both have got their AV disabled as I have found sometime this affects shells. I have also completed challeneges on the computer not recieveing the shell before.
What are my next logical fault finding steps? As I am really stumped on how this is happening.
p.s. The computer A which works is a Dell Laptop, and the PC B that doesnt is a Desktop running on the same wifi.
Many thanks for any help I get in advance.
