Solaris 10: NFS mounting issue

Hi,

I posted it on another section, but seems I got no answer, so have to post it again here.

Here is situation.

Sun server A can mount other NFS from SUN servers fine, but it only can't mount NFS share that is from Windows server 2003 (server B)

It was fine, but all the sudden it failed, ONLY can't mount from window server B.

But other sun servers can mount NFS share from Windows sever B, no problem.

There is something wrong for sun server A, but I couldn't find out that caused that. And reboot is the only way for me to fix this issue.

If I tried to enter that mount point, like "cd <mount point", it just stuck there, and I have to do Ctrl+C to stop it, then I got ".... bad directory"

Any suggestion what to check?>
