We're trying to connect an email server with a NAS device. Email server runs over Windows 2003 Server and NAS device with Open-E. No "Active Directory", just shared folders with CIFS.
In order to ensure the connection between them, we've changed the user that runs the email server and we've given to him read/write permissions.
The problem comes with Plesk Control Panel wich runs on the email server and lets the users manage his mail domains. With Filemon (http://technet.microsoft.com/en-us/sysinternals/bb896642) we've discovered that Plesk retrieves information about the size of the folders with the process 'sysinfo.exe' wich is loaded by the SYSTEM user. As I said before, no active directory, just shared folders with CIFS. Obviously this access results in 'ACCESS DENIED'.
As long as I know, with this schema, problems with permissions are avoided ensuring that users and passwords are identical in both devices. As far as I know, SYSTEM user can't be manipulated in order to achieve this.
Is there any way to get SYSTEM user reading and writing over the NAS?
Thanks a lot,
