When trying to publish an image in PVS, you will see the following error:

[2017-11-15T16:04:11.104Z] ERROR: pvs-connector/10307 on localhost.localdomain: (reqNum=1663)
    [c33700a0-ca47-11e7-af9c-83455e914109] -> Operation 'pvs:UploadDiskOperation' has failed: Failed copying file to D:\xxxx\xxxxxxxxxx.vhd.  The operation timed out
      The error occurred while the remote file was being processed.

When we publish an image to PVS we need to talk on port 3009.  We can tell we are communicating when we look at the file called BitTransfer.log in the Agent log.  The log from every Agent that is registered with an ELM should be captured inside ELM logs, when you do a log export.  Look for a file named  fqdn-of-the-host_DATE_TIME.tgz.  If the log retriever from the Agent fails, there will an error log somewhere in ELM logs.

Things to check on the PVS server:

1. Double check the firewall settings.  BITS may need to be whitelisted
2. Change the account used in the Connector configuration
3. Verify that the UAC is turned off
4. Reboot the ELM

If the BitsTransfer.log is 0 bytes you know that the process to push the data from the ELM to the PVS server, never started.  At that point start checking the above 3 options.

Also, the ELM needs to be rebooted after changing the IP address.  Otherwise the ELM may place the old IP addresses in its constructed URLs.
