Troubleshooting Load Balancing Issues

This section describes how to troubleshoot some issues that you may encounter in the Load Balancing setup.

Health test feature failure in ARR proxy with SSL

Issue: If the ARR Proxy does not trust the backend server’s Digital Certicate, the health test may fail with the Error Code 80072F8F.

Resolution: Import the certicate that is used to setup SSL on the WDM management server onto the Trusted Root Certicate

Authorities store for a local computer on the ARR Proxy system by referring to technet.microsoft.com.

ARR Proxy Returns HTTP Error Code 502.3

Issue: The ARR Proxy returns the HTTP Error Code 502.3 for older WDM Agents (HAgents) that do not send the HTTPHEADSUPP=2

tag when they are checking in. If the HAgent does not send the HTTPHEADSUPP=2 tag while checking in, then the Management Server

does not send the HTTP status code header (200 OK) in response and the ARR proxy returns the error. Only the clients sending the value

2 are supported in load balancer setup.

Resolution: You can run the following query on the WDM Database and read the value:

SELECT [HttpHeadSupp]

FROM [ClientNetwork]

where [MAC] = <ClientMac>

110
