<p class="MsoPlainText">Hello Volker, I haven’t been able to find the source of those undocumented bits in the Flags field from all of the branches we make builds from. I wonder if hey slipped through patch/maintenance builds. To figure that out, I need the
copies of srv2.sys, ntfs.sys files from C:\Windows\System32\drivers on your SMB server. Would you be able to upload them to your workspace for this incident ?<o:p></o:p></p>
