OSD, ADSI Script run fail in WinPE5.1(ADK 8.1)

I want to run ADSI script to check if there is a computer in domain.  If I find this computer account already exists in domain then you can join domain. My script as below.

But it can't work in winpe. it said "Table does not exist" of code "Set objRecordSet = objCommand.Execute". BTW, this script run fine in standard system and the boot image had been installed all cab plugin(Script,WMI...).

I know it should miss some ADSI related plugin. I want to know how to make this script work or how to check if there is a computer acount in domain.
