Purpose
A pull copy operation on a target computer failed. The most common cause is that the target computer cannot see or access the file being pulled. This can be due to a name resolution or authentication problem preventing the network path from being accessible to the target. This may also be due to the deployment using the option to "Run as Local System" which causes it to run under the computer system account which won't, by default, have access to network resources.
Resolution
The error message will contain additional information about the cause of the error. Make sure that the path in question can be seen from the target, the deployment doesn't use the "Run as Local System" option, and the credentials used have access to the location the files are being pulled from.
Note: The Pull Copy mode does not currently work with LAPS credentials.
