Mike - I've been following this thread since we too are experiencing this
exact same issue. We are running JCIFS 1.3.8 on AIX 6.1 and accessing a Win
2003 share. Our LDAP user takes upwards of 10 minutes to display data while
a local user on the Win 2003 share displys nearly immediate.
Throughout this thread you imply something may be wrong on the AIX side:

>"Because the server is AIX, you're seeing an unusual error condition."
>"A wild guess is that the AIX side is just misconfigured."
>"the AIX server thinks your a DOS attach"
Are you suggesting something is amiss at the AIX OS Level or a faulty
configuration at the jCIFS client configuration?
Coould you suggest some areas where I could look at the AIX level to see
what may be misconfigured on the AIX Side?
