>Does anyone know how to open the Windows Explorer Map Network Drive dialog from Fox?

You can map network shares without this dialog.

if !directory('p:')
   wshshell=CREATEOBJECT('wscript.shell')
   wshnetwork=CREATEOBJECT('wscript.network')
   wshnetwork.MapNetworkDrive('p:','\\myserver\mypath',.f.,'Username','Password')
   wshnetwork=.null.
   release wshnetwork
Endif

Replace .f. with .t. to get a persistent mapping.
