Access Error when using the GetFiles in RTC

Hi guys,

I wrote a code that will check a folder on a shared drive, see if there are any files on it, then process those files and move them to a different folder on the same drive once processed.
I used the following DotNet libraries...

DirectoryInfo_dn = 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.IO.DirectoryInfo
Files_dn = 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Array
File_dn = 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.IO.FileInfo

and in getting a list of the files in the directory to begin with using Files_dn := DirectoryInfo_dn.GetFiles();, I am getting a permission error.
"Access to path '\\FS02\Advance\Invoice' is denied

I checked and I have full rights to the folder. The user that starts the middle tier server also has full rights, so I am stumped whom to give access to the folder.

Any input would be greatly appreciated.
