A vendor is attempting to map and preserve a network drive using nt authority/system; so it stays persistent when the interactive session of the server is lost. They were able to do this on one server (Windows 2008 R2) but not a second computer (also Windows 2008 R2).

I am unsure on how to set up a "machine account mapping" which will preserve the drive letter of the Netapp path being mapped, so that the service account running a Windows service can continue to access the share after interactive logon has expired on the server. Since they were able to do this on one server but not another, I'm not sure how to troubleshoot the problem? Any suggestions?
