Access Denied

[Van Hoff, Mike]

All,

I am running 3.0.33-3.29.el5_6.2 on RedHat Enterprise Linux 5
I use AD authentication for sharing directories / files.  No Printer or desktop login.

There are multiple netbios names associated with this server.
Over the past two (2) weeks, some of our processes have been getting "Access Denied" when writing files.
Ex.  Ftp process runs on a windows server under a user that has access to the samba share.  This process ftps a file from an external vendor and writed it to the unc share (\\sambaserver\share\subdir\filename.txt) but get access denied.

Now this has worked for the past year until as I stated about 2 weeks ago, and is and intermittent issue.  I cannot reproduce the error on demand, but it seems only to happen when the ftp process is running from our automation software.
The samba logs only show this " linux_release_kernel_oplock: Error when removing kernel oplock on file... "

Any suggestions will be greatly appreciated.
