EWF error message. error 87 ?

[Carl Johan Jensen]

Hello !

I have created an XPE image including the EWF (ram based). Exact following
the instruction given on Microsoft homepage, everything
seem to be OK until i try to disable the EWF (should be possible).
I follow the steps: Run FBA, verify EWF, configure network and users, run
etprep /delete, reboot, verify EWF enabled,
then I try to disable EWF with ewfmgr /disable - this last command says:
unable to set ewf parameters error code 87 ?
Enabling or displaying status of EWF gives good meaningfull responses.
Any good ideas of how to debug EWF behaviour ?

Hi Carl,

This is expected behavior since you have deleted EWF volume.

disable is not supported.
You must use commitanddisable switch.

Also if you want you can use registry configured RAM EWF from the TD. (No need for creation of temporary config EWF volume).

Find my documentation and component at www.xpefiles.com

Best regards,
Slobodan

Carl Johan,

Since you don't have EWF Config partition in place (you deleted it with "etprep /delete"), you won't be able to use "disable"
command.
This is a restriction of the RAM based EWF without EWF Config partition (the state is stored in the registry and the only way to get
that registry change persisted to disk is to commit the overlay).

Don't delete EWF Config partition if you really need to use "disable" command.
Or use "commitanddisable" command instead.
