20

Make Sure That User Group Everyone Has Full Security Control To Read & Write To The Disk

Once They Get There

21

Double-Check SharesIf Computers CS-3 & CS-1 Were To Be Used For The Transfer, You Should Be Able To Log Into CS-1 - Copy Files To The CS-3 Share & Delete Those Files.

You Should Be Able To Do

Likewise On CS-1. Check Them To Make Sure The

Shares Are Correctly

Configured!

22
