I set up a NFS client service on windows 2008 Server R2 standard edition, using GID/UID in registry. My application can read/write files on remote Linux NFS server. But the bad news is that: every about 20-30 minutes, the time of read/copy file goes up from 0.020 s to 30 s!! It's unacceptable for me.
I use Wireshark to analyze network data, find the Linux NFS server responds very quickly to NFS client.
I use Java/C to test this scenario, and it always happens every 20-30 minutes.
My NFS client mount config is :mount -o mtype=soft retry=10 timeout=6 casesensitive=yes anon
BTW, I found some event logs like:
Windows(R) Lightweight Directory Access Protocol (LDAP) failed a request to connect to Active Directory Domain Services(R) for Windows user <DOCSCR1\Administrator>.
Without the corresponding UNIX identity of the Windows user, the user cannot access Network File System (NFS) shared resources.
Verify that the Windows user is in Active Directory Domain Services and has access permissions.
I have google a lot, but no related topic.
Hope for help!
