Technical Tip: FSSO - How to check the DC agent version

[FiFa_FTNT]

Description

This article describes recommendations regarding how, when upgrading the Collector agent component, it is sometimes forgotten to also upgrade the DC agent on remote Domain Controllers. Though newer FSSO versions are backward compatible and support older DC agent versions, it is strongly recommended to upgrade DC agents to same version as Collector agent.

Scope

FSSO - DC Agent.

Solution

To verify the deployed DC agent version:

1. Open %windir%\system32 and locate dcagent.dll.

2. Right-click on the file and select Properties.
   
   
3. Select the Detail tab and check File Version.
   
   

A quicker way to check the DC agent version is via PowerShell. Open the PowerShell CLI as administrator (elevated prompt) and execute the following command:

(get-item "c:\windows\system32\dcagent.dll").VersionInfo

Output of the command:

ProductVersion     FileVersion      FileName
--------------            -----------           --------
5.0.230.0           5.0.230.0        C:\windows\system32\dcagent.dll

4. Confirm that the DC agent is from the same version as the Collector Agent.
   
   
5. If not, push a fresh DC agent version from the Collector Agent.
