Hi Guys

I am having a big issue with a Sharp MFP that is not seen by a Windows 2012 Server.
I mean that in Network MFP with can be seen by all the clients, while Server With is not seeing MFP. (No WebPage, No Ping, No Print).
I tried whatever I know about WINServer (Firewall, and Local Policies) but no way. FW is updated.
MFP has no IP filtering.

A Ricoh MPC2550 on the same Net "" is well seen and printing.

What can I check? Any clue?
