A Discover scan will not start and errors out.

The customer has the proper credentials and access to the fileshare, yet the scan will not start.

The following error may appear in the Vontu UI in the Scan Detail screen:

WARNING: Failed to read \\servername\fileshare; error: CreateProcess: C:\Vontu\Protect\bin\smb.bat l: "\\servername\fileshare" "Domain\scanner_user" <password> error=5

There are a couple of solutions to this issue:

Solution 1 (preferred solution):

1.  Go to C:\WINDOWS\system32, go to properties for cmd.exe and then security tab. 
2.  Verify that SERVICE has access to it.  Make sure it has read & execute and read permissions 
3.  You may have to add SERVICE and give it the permissions as described in step 2.
4.  Restart the Vontu Monitor service before running another scan.

Solution 2:

Add the user running the Vontu Monitor service on this Discover server to the Local Admin group.
