Suspend BitLocker fails in Task Sequence with Invalid Namespace error 0x8004100E

When you try suspend BitLocker via Task Sequence step it fails. On checking smsts.log you find out the below errors

Even if you try to run manage-bde -protectors -disable c: in an elevated command prompt it fails with “Invalid Namespace” error.

This problem occurs if the Bitlocker WMI class (win32_encryptablevolume) is not registered or missing registration.

To resolve this problem, you have to re-register the BitLocker WMI (win32_encryptablevolume) class.

Open an elevated command prompt and type the following command:
mofcomp.exe c:\windows\system32\wbem\win32_encryptablevolume.mof

If the file successfully compiles you will receive the following message:
Microsoft (R) MOF Compiler Version 6.1.7600.16385

Parsing MOF file: win32_encryptablevolume.mof

Now re-run the task sequence and it should successfully suspend and enable BitLocker.
