Error connecting to port 445

[Panagiotis Malakoudis]

I'm experiencing some problems trying to setup a samba bdc (that will server
as a backup for a samba pdc).
When I use rpcclient to add the bdc to the pdc domain using the -j switch I
get the error message "error connecting to 10.0.1.32:445 (Connection
refused)"
The same error message I get even when I simply try rpcclient -S
thepdcname -U root%password -W domain

Any hints on that one?

Best regards,
