Random behaviour accessing a share

[Waldy]

Hi there,
I have a C# Windows Service project that is checking a network
share for new files and processing any that are found. The share has been
given Full Control to the group Everyone. However, I am getting random
behaviour where one time the code will work fine and the next time I will
get an access denied error. What is going on?

Message: Access to the path '\\Uksrvtl16a-6193\AATest' is denied.

searchOption)
at System.IO.DirectoryInfo.GetFiles(String searchPattern)
at
Touchpaper.ActiveAssistance.OfflineController.FileProcessor.ProcessFiles(String
DataFolder)

The code I'm using is:

protected String FindNextFile(String FolderName)

{

DirectoryInfo di = new DirectoryInfo(FolderName);
FileInfo[] rgFiles = di.GetFiles("*.xml");

if (rgFiles.Length > 0)

{

return rgFiles[0].FullName;

}

else

{

return null;

}

}
