HP Web Jetadmin - Discovering PC-Connected Devices

3. If no Hosted Endpoints are listed in the log file, check for errors such as:

Exception caught in the function OnReceiveRequest...Object reference not set to an instance

of an object.

If this error is listed then the proxy agent cannot connect to the printer. Likely another

application is using the socket connection that the WS Proxy agent needs. This could mean

that VM workstation is installed on the same client as the WS Proxy agent.

4. Verify that the latest version of the WS Pro Proxy agent is installed. The version will be

displayed under Control Panel, Program and Features in the Version column and the name.

WS Pro Proxy agent before 10.3.1, will only display the version in the version column or

might not show any version at all.

DISCOVERY LOGS

Additional log file functionality exists within HP Web Jetadmin that allows administrators to

understand and troubleshoot PC-connected device discovery attempts. The following steps can be

used to enable and gather logging details for the HP SNMP\WS Pro Proxies and WMI.
