Hi jdmcdaniel3,
I have tried the two things you recommended. The first was to adjust the server-side smb.conf to the settings in your example, comment out the the Domain Master setting, and make corrections to the workgroup setting on the client side to match the server. After restarting the smb and nmb services, the server and client show exactly the same behaviors; mount.cifs works fine and smb:// protocol times out.
The second thing was to completely start over and configure samba from scratch with your sact tool. The interface and instructions are very nice. mount.cifs functions normally whether performed on the server or from the client. smb:// from dolphin is another matter. smb://192.168.1.7/uname timesout when performed from any location.
It seems like there must be something fairly obvous that I am missing given that mount.cifs functions normally.
