10.10 smb authentication
To Apple
I currently have a few clients that have upgraded their mac OSX to 10.10 from 10.8 and 10.6. These client have a copier which uses SMB to connect to their machines for file scanning. Ever since the update, the machines will no longer authenticate and fails to connect to the client machines. I created new user account, I check permissions from other non mac PC's and everything connects fine except for these copiers. Both these copiers are OKI brand MC862 and have worked flawlessly until now. They will connect to every other machine on the network, MAC or PC except these 10.10 machines ( which worked prior to update ) How can I fix it so the OS will allow these copiers to scan to a folder on their machines.
