Hi friend, here's a networking problem for you to solve ...
There's a multi-function-printer shared between two local (wired) networks via a router. The networks consist of workgroups (no domain) and the problematic targets consist of a Windows 2012 server machine and some Win7 (unknown edition) clients. Windows firewall is OFF.
The printer should push scanned documents thru the router onto a share on the Windows 2012 server machine. But it doesn't. The printer couldn't access the share (or similar shares) on the server and the clients. The permissions of the share should allow the access.
printing to that printer from all machines works well,
ping runs thru seamless, and
a latop with Win7 pro (which usually resides in some other domain), with a similar share, placed into the server's network segment, could receive the printers scanned documents,
I presume the router config to be OK.
The shares could be seamless accessed by machines from within the same network segment.
Based on those facts, I suspect that there's some obscure windows networking setting that denies the access to shares from machines outside of the own network segment ... but I couldn't find it.
Any idea where to search for it ?
