Isn't maclan an AFP server for Windows? You should be able to just connect to the server using the built-in SMB support of OS X.
In the connect window, instead of using
AFP://<servername>
use
cifs://<servername>
or
smb://<servername>
That said, the SMB support in Jag is still a bit buggy, it doesn't allow filenames with []'s in the filename for example. And every version of 10.2 except for 10.2.6 and 10.2.4 had some pretty serious data corruption bugs as well.
