Issue/Introduction

We are unable to deploy many/most probes to Windows Servers. Robot_update is also failing on the servers. 

We receive a message like: "Installation of section win64 failed"

The controller log on the target machine shows errors like the following:

Aug  1 05:04:15:745 [4572] 0 Controller: inst_file_next: Unable to append to file robot/pkg/temp/vs2017_vcredist_x64.exe.tmp 

The filename may be different but in all cases, a .dll or .exe is involved.

Environment

DX UIM 20.4.* / 23.4.*

Cause

  • The Windows Defender Advanced Threat Protection (formerly known as Windows Defender Endpoint.) is blocking this operation. (MsSense.exe)
  • The Realtime scans by Windows Defender interfere with the ability of DX UIM to transmit / copy these files.
  • To prove this is the case, using the Procmon Microsoft tool you can proof MsSense.exe is blocking the files:



  • OPLOCK means that MsSense.exe has put a lock on the file so that it can scan it, without being interrupted.
    This lock is the main cause of the issue. SUCCESS means it was able to successfully scan it. 
    In the example above, OPLOCK prevents the files from being updated.
