I have solved this problem!
1)Run secpol.msc set Local policy. Enable Let "everyone" apply to anonymous. (I guess translate to English should be this.)
2)Then in SFU set "user name mapping" , let user "Guest" to "root" and group "Guests" to "root".
3)set your want NFS's directory have "everyone" user and let it have all control permission.
4)In linux mount the NFS is OK! Can access!
For example:
Code:
mount -t nfs 172.16.7.45:/temp /mnt/nfs
Use command "showmount -e IP_address" can see the target directory path.
