A server processed by a job fails with the following error: Error: Failed to connect to guest agent. Errors: 'Cannot connect to the host's administrative share. Host: [<hostname>]. Account: [...]. Win32 error:The network path was not found. Code: 53 Cannot connect to the host's administrative share. Host: [<ip>]. Account: [...]. Win32 error:The network path was not found. Code: 53 Note: This applies to both VMware and Hyper-V environments.
This error occurs when Guest Interaction Proxy ( vSphere | Hyper-V ) fails to connect to the Guest OS while attempting to perform Application-Aware Processing ( vSphere | Hyper-V ). The Guest Interaction Proxy will attempt to connect via the hostname first and may fail if it cannot resolve the IP address. If the Guest Interaction Proxy Fails to connect to the guest Admin Share by hostname, it will try to use the IP reported to the Hypervisor. The Win32 error, "The network path was not found," is received by Guest Interaction Proxy from the OS when it attempts to connect to \\<guest-hostname\ip>\admin$
The key to troubleshooting this issue is identifying the environmental problem preventing the Guest Interaction Proxy from connecting to the admin$ share of the server being processed. Tip: To test connectivity to the admin$ share rapidly without running the job, use the "Test Now" button on the Guest Processing tab of the job to launch the Guest Credentials Test. Troubleshooting: Test connectivity to the admin$ share (for example, \\<hostname>\admin$) from the Guest Interaction Proxy with the same credentials specified in the Guest Process section of the job. Test from multiple machines, including the Veeam Backup & Replication server and other Guest Interaction Proxies to isolate if there is a connectivity issue specific to one of the Guest Interaction Proxies Make sure the Guest Interaction Proxy can access the VM ping the hostname and IP Test connectivity to port 445
