Samba can be a PDC, allowing Windows clients to join a single line domain name and then access domain resources (such as roaming profiles) as though the domain were Windows NT-based. When you set this up the default behavior for Mac OS X Server based domains is to create a drive mapping for H: to the users profile path (as specified in the homeDirectory attribute) on the server. H: is kinda’ low for some computers with a lot of drives and it can also conflict with other drive mappings you may choose to use. Therefore you may find that in some cases you need to change the H:.
To do change the drive letter that the logon drive uses, look to the /var/db/smb.conf file. Here, you’ll notice a logon drive variable which is set (funny enough) to H:. Specify any letter of the alphabet that you’d like it to use (preferably higher than H:) and then save the changes to the file and restart the service. Now you should see a new drive letter assigned at your next login event. You can also change a number of other variables in these files, so it’s recommended to back the file up before making any changes.
