I'm sorry....
I have to write again because unfortunately and unexplainably even if the LmCompatibilityLevel is set on 1 or 2 it suddendly stopped working so I'm not able anymore to scan to smb even if I was able to do that before.... I have also tried to disable the 128bit option but still no luck! The only changed thing since it worked is that Windows installed some updates...!
Any further ideas?
Thank you
Karina
