When I try to map a drive to CIFS Server (I have tried '\\myserver_a\alfreco' and just '\\myserver_a' - not sure which is right) it asks for a username and password.
What is it looking for - I have tried my domain username and password and admin and admin and got nowhere - help!
What version are you running? Is it a default installation (from fresh or did you have a prior installation)? What happens on the web client? Have you seen this? http://www.alfresco.org/forums/viewtopic.php?t=1158
