Assuming that HideCalc is simply giving you the DWORD values for your specific drive letter combo, you'd need to use that value to set two policy settings: NoDrives <- Hides them in the common file dialogs. NoViewOnDrive <- Prevents user from typing drive letter in common file dialogs. Apps that don't use the common file dialog windows will ignore these settings. Typically these would be older apps. Both settings would be placed under HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Beckett, William (Bill) Sent: Thursday, September 14, 2006 11:07 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Hidecalc Question for anyone who has used HideCalc in a TS environment. Does this template merely "hide" the drives or does it prevent a user from using it? In other words, if a user went to explorer and type in M:\, could they get to it?
