[Samba] Shares

[Sandbox]

Hai,


As I know i could open my shares via domain eg: \\domainc.com\share
I have 2 samba 4.1.5 server and one win2003 DC.
Succesfully made a clustered filesystem so now both servers (except
win2003) can open the shares.
My problem is: i succesfully opened the share yesterday, it worked well one
time but since that i couldnt open it via \\domain.com\share only via
\\dc01\share or \\dc02\share.

Could you help what could be the roblem?

Thanks,

Robert
