Hi again,
Just to review the symptoms so far::
As noted above above, during normal operations the systems log has a message every few minutes that NcbService is not a valid win32 application, but it is in the task manager services list, as stopped.
Ran sfc scannow this AM, It ran for several minutes, then dIed in the same ~43%, with the same resource protection error msg. Cbs log had 2 messages associated with the ncbservices.dll file. SFC then stops. The Applications log has 3 msgs from Windows error
reporting. Nothing in systems log. Running dism gives a similar dll msgs. Will confirm the sequence of errors.
I downloaded 1803 iso from tb.rz-adguard.net. The only 1803 listed was version 17134.1. Winver says that 17134.1099 is the current running version. If I try to run dism using the iso as a source, does that mean it might try to repair this installation with
a file 1 1/2 years out of date?
thanks for your patience,
pete vh
