Remote Agents

Trouble installing remote agents

If you are having trouble installing the SentryOne Document Remote Agent, enter the following command in the command prompt:

C:\Users\<Username>\Downloads>SentryOne.Document.Installer.msi /l*v Installer.log

This command creates a log file at the installer.log location. Proceed through the installation process, and once you reach an error, send the log file to for further assistance with your installation.

Remote agent log files

The general log file (used during the startup and initialization of remote agents):


The main log file, which is specific to the installed remote agent (friendly/service instance name):

%ProgramData%\SentryOne\SentryOneDocumentRemoteAgentLog_{Remote Agent Name}.log

For a more detailed log, you can view the log output for your on-premises installation at the following path:

C:\Program Files (x86)\SentryOne\SentryOne Document Remote Agent\SentryOne.Document.RemoteAgent.exe.config

Note:  Logging is set to record any error by default. If you want your log to record more detailed data, you can change this configuration to debug.

HTTP Error 401.2 - Unauthorized

You are not authorized to view this page due to invalid authentication headers.

Most likely causes:

  • No authentication protocol (including anonymous) is selected in IIS.
  • Only integrated authentication is enabled, and a client browser was used that does not support integrated authentication.
  • Integrated authentication is enabled and the request was sent through a proxy that changed the authentication headers before they reach the Web server.
  • The Web server is not configured for anonymous access and a required authorization header was not received.
  • The "configuration/system.webServer/authorization" configuration section may be explicitly denying the user access.

Example of a 401.2 Unauthorized error

What we've seen this mean:

This error has shown up when the Windows Authentication feature for IIS has been turned off or disabled. Windows Authentication is a requirement for the self-hosted version of SentryOne Document. There are some examples below, but always check with the official Microsoft documentation for up-to-date information on these features and settings.

Step 1. Ensure that Windows Authentication is turned on under Windows Features:

Windows Authentication must be turned on

Step 2. Ensure that Windows Authentication is enabled for the SentryOne Document API and SentryOne Document Host Sites in Internet Information Services (IIS) Manager.

Windows Authentication must be enabled for the SentryOne Document Sites
