Handling Process

  1. Use DebugViewer to capture the VDI client logs during operation (update) and save them as a file for analysis.
    file

  2. Search for "SendUpdateResultToQuestor" in the log file and find the name of the control with "update state is 2".
    file

  3. Find the version number of the control with update state 2 in the registry of the VDI client. In this case, the version number is 5.4.2.203.
    file

  4. Log in to the VDC backend, view this two files, and compare whether the version numbers of the controls recorded in are consistent.
    /sf/share/app-win/WindowsModule.xml
    file
    /sf/mfs/share/htdocs/com/WindowsModule.xml
    file
    Registry: 5,4,2,203
    /sf/share: 5,4,2,203
    /sf/mfs: 5,4,2,2020
    In this scenario, make a backup of /sf/mfs or rename it to other name.
    Make a copy of /sf/share and name it as /sf/mfs.
    Note: If all the version are consistent, gather information and consult R&D.

Root Cause

When the client connects to the VDC, it will download the WindowsModule.xml file from the VDC to the local %temp% directory.
Then compare it with the control version recorded in the registry, and update it if it is inconsistent.

Solution

Modify the WindowsModule.xml file on the VDC
