Guy,

You can create .vbs files that will map and unmap drives on the fly.
These Windows script files can be called by Scheduler or VFP.
Of course your admin username and password must successfully authenticate in any server you are mapping.

This code will map 5 drives:

On Error Resume Next
Set objNetwork = CreateObject("WScript.Network")

objNetwork.MapNetworkDrive "I:", "\\Aseserver\I", True
objNetwork.MapNetworkDrive "J:", "\\Aseserver\J", True
objNetwork.MapNetworkDrive "K:", "\\Aseserver\k", True
objNetwork.MapNetworkDrive "H:", "\\Aseserver\k", True
objNetwork.MapNetworkDrive "S:", "\\Shopserver\Data (D)", True

This code will unmap all drives:

On Error Resume Next
Set objNetwork = CreateObject("WScript.Network")

Set colDrives = objNetwork.EnumNetworkDrives
i = 0
For i = 0 to colDrives.Count-1 Step 2
   strDrive = colDrives.Item(i)
   objNetwork.RemoveNetworkDrive strDrive, True, True
Next

Thanks
