Don't use * as a wildcard in /etc/exports. It says explicitly in the
documentation that this can happen. * requires reverse DNS.

Hell, which document?? man exports even didn't mentioned the word
"reverse" nor 'DNS'
If you don't want to have reverse DNS, use IP notation 0.0.0.0/0.0.0.0
instead.
strangely, even if I use 0.0.0.0/0.0.0.0 (and restart nfs) I still
cannot connect, behavior:

If I use 0.0.0.0/0.0.0.0 in place of wildcard (*), there is no longer error
message in /var/log/messages. But still Windows client cannot connect..
Some times, the Windows client ask for a username and password, because
this is anonymous share I don't know what to fill in, typed several
username like 'guest' 'anonymous' and finally some real username and
password but still no access. Press "ESC" to get rid of login dialog, trying
connect to NFS share again got "Network Path Not Found" error from
Windows client. During all these, no error messages produced in
/var/log/messages.


Hello Zhang,
Have you considered that it might actually be a security issue? When
you installed the MS SFU NFS client how did you answer the Username
Mapping Server question?
