REQUEST: RAM Reg EWF DUA example

[Guest]

I've read about deploying EWF-based systems on MSDN and other places. My
current build implements the RAM Reg EWF and I wish to update using DUA.

My dilemma takes on the following form:

1) I've successfully implemented the DUA, pulling .dup files and update
content from an HTTPS site.
2) The update arrives at the client runtime, pulls necessary files from the
client, and balks at creating processes or executing new commands.
3) Command:

EXECUTEPROCESS,,,,c:\windows\system32\cmd.exe,,c:\windows\system32\cmd.exe /c
"c:\dua\demoMsg.vbs",DAYES,4294967295,,DASEC_REV,,,,DASEC_REV,,,,,,c:\windows\system32,1,,WinSta0\Default
4) Event Log shows of the following error:

Yields:
Event Type: Error
Event Source: DUAgent
...
Description:
DUAgent Service - Error Executing Command CreateProcess. (%3).

I've also gotten the following error while futzing with the line:

Event Type: Error
Event Source: DUAgent
Event Category: None
Event ID: 125
Date: 9/25/2007
Time: 2:02:09 PM
User: N/A
Computer: OEM-X0ZNM35MCWD
Description:
DUAgent Service - Error Executing Command CreateProcessWithLogonW. (The
specified service does not exist as an installed service.
).

I'm not sure how to go about correctly executing new processes and/or
running my vbscripts via DUA. I've tried using output from DUAScriptGen to
guide my endeavor. But, it appears that I haven't configured the command to
run appropriately for my system. I would appreciate an example or two to aid
me in the process.

I understand there is a process involving a mixture of disabling EWF,
possibly rebooting, performing commands at next boot (?), polling for a
second DUA script (?) and/or reenabling EWF before rebooting.

I would also appreciate a list of the actions to be performed for a RAM Reg
EWF system (such as mine) using DUA. Examples would be like Xmas-come-early
as well. Thankyou.

i've seen the "The specified service does not exist as an installed service."
message before (but not when using DUA). the cause was that i did not have
the RunAs service installed on my image.

Without that service your application which you run as part of the device
update MAY not have the necessary priveleges to do what you need it to do.

Can't help with the EWF stuff, never used it.....
