Environment

Issue



Dagent does not function in Windows Embedded System 7, and/or causes the write filter to behave abnormally.


Error



When the Dagent is installed the EFW shows in a “Yellow” state meaning the drive is ready for changes. This can be manually set to a “Green” state or a reboot will put it back to “Green”. This does not mean the drive is protected. Still able to write to the drive however even though able to write to the drive in a “Green” or “Yellow” state am not able to commit those changes even though it says they are being committed.


Environment



Deployment Solution 6.9 SP5 MR1 and previous versions


Cause



Installation of the Dagent from Deployment Solution SP5 MR1 or prior causes the EWF (Enhanced Write Filter) to not protect the volume of the Thin Client. It has been found that whether the install was done through the auto-upgrade or a manual install does not change the attributes of whether the EWF will work with the Dagent.


Solution



This issue has been resolved in Deployment Solution 6.9 SP5 MR3. See TECH201480 to download Deployment Solution 6.9 SP5 MR3.
