hi matt thanks for your reply.
Yes, this is sccm boot image created by sccm 2007.
So, i had added HTA Support as below
Dism /Mount-Wim /WimFile:C:\winpe_x86\winpe.wim /index:1 /MountDir:C:\winpe_x86\mount
Dism /image:C:\winpe_x86\mount /Add-Package /PackagePath:C:\Program Files\Windows AIK\Tools\PETools\x86\WinPE_FPs\WinPE-HTA.cab
Dism /image:C:\winpe_x86\mount /Add-Package /PackagePath:C:\Program Files\Windows AIK\Tools\PETools\x86\WinPE_FPs\en-us\WinPE-HTA_en-us.cab
Dism /Unmount-Wim /MountDir:C:\winpe_x86\mount /Commit
copy wim file, update bootimage and distribute to dps.
Ran test, same result.
So, for testing, unmount wim file and copy hta to windows\system32\hta folder.
In TS, I ran command line with x:\hta to windows\system32\hta\select2.hta and it works..
Any suggestion????
