UPDATE: Jun 23, 2007 - I have created a an INF installer for Win Pe 2 to make the manual changes i documented below. There is ALSO a good ADSI INF Plugs in at : http://www.deployvista.com/Repository/Wind...73/Default.aspx Please email if you have need. J P Morgan - j.p.morgan@lmco.con Ryan, As i explained on the Phone, the process that i got to work for me was: First, Mount the BOOT.WIM, from Win Pe 2 creation output sub-dir, and make some Registry changes to the SYSYTEM hive Secondly, copy EPHD files into the appropriate sub-dirs --------------------------------------------------------------------------------------------------------------------------------------- (A) Mount BOOT.WIN and make Registry changes to SYSTEM hive. (1) I wont go into HOW to Mount the BOOT.WIM, using imagex, i assume you know how to use WAIK and create the 'WINPE_X86" sub-dir ie : imagex.exe /mountrw c:\winpe_x86\iso\sources\boot.wim 1 c:\winpe_x86\mount (2) Once the BOOT.WIM has been create and Mounted, EXECUTE REGEDIT.EXE (a) LOAD the 'SYSTEM' Hive UNDER HKEY_LOCAL_MACHINE the path would be : c:\winpe_x86\mount\windows\system32\config\ and the file is SYSTEM (B) give it a Hive name of EPHDSYSTEM (FOR EXMAPLE) under the EPHDSYSTEM\CONTROLSET001\SERVICES KEY CREATE A NEW 'SERVICE" KEY (1) Create a Key called "ephdxlat" (without the quotes) (a) under this key create TWO DWORD keys (1) start DWORD 3 (2) type dword 1 (d) Edit the Registry key value under [HKEY_LOCAL_MACHINE\EPHDSYSTEM\ControlSet001\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}] (1) Edit the "UpperFilters" Key and ADD the text "exphdxlat" (without the quites) such that the MULTI-SZ has a value of : PartMgr ephdxlat THAT SHOULD DO IT.. NOW , UNLOAD the Registry Hive . (B) Copy files Add these files to the build directory and place them in the /windows/System32/. EPHD_Access_utility.exe EPCL32.dll EPCRYPTO.dll The next file is to be added to the /windows/system32/drivers/ EPHDXLAT.sys Now, UNMOUNT and COMMIT the changes to the BOOT.WIN NOW, copy the NEW BOOT.WIM to your Flash Key (thats what i use) or recreate your ISO Now, BOOT from your WinPe 2.0 media Now, at the Winpe 2 Dos prompt type x:\windows\system32\EPHD_Access_utility.exe Now enter the ID and Password You probably will get an ERROR box complaining about "not running Defrag", Click OK to continue You should then get a dialog box that you now have access to the encrypted drive.. Click OK You should now 'see' the files on the "C:" drive. Comments: I find the vendor , "PC Guardian" to be somewhat arrogant and hard to deal with. Their reply was "we dont support vista". they ALSO require you to have a maint contract, even to look at their FAQS. What gives with this, they must think that their product is the greatest thing since sliced bread. I dont work for the company, i ONLY used their product TWICE, to see what was so great about it, and within two days i was able to get it working with Win pe 2.0, They have FULL access to the sources.. I HOPE the above works for those that need this capability. Enjoy.. J P Morgan - j.p.morgan@lmco.com
