Issue/Introduction

A site server may show warnings in the logs stating things like Block 0 (2471/4785) is invalid for file.  You may also see errors stating: Error while downloading package:  An unexpected network error occurred (0x8007003B).  You may also see messages about retrying the download in the agent UI > package server tab.  Another key piece of this issue is you may be using an alternate download location for all of your packages on your site servers.

 

 

Environment

Release: 8.6

Cause

Incorrect permissions, permissions not inherited properly.

Resolution

On the top level of your alternate download location, you should set the proper security and then inherit the permissions to child objects.  After doing this, the package server will start to properly download package files.  The following permissions should be present and inherited down to all child objects:

Everyone - Read & execute

Administrators - Read & execute

SYSTEM - Full Control

IIS_IUSRS (LocalServerName\IIS_IUSRS) - Read & Execute

NETWORK SERVICE - Read & Execute

You may also need to reference FAQ on Package Servers regarding EnableDACLManagement and NoPACLockdown.  It's best to leave these settings OFF and see how the package server behaves.  If you notice the permissions mentioned above, changed or not created on new folders (Packages), then you should try enabling those options.

It's also best to consider using the default package server location instead of an alternate download location.  Just install the package server agent to the largest drive on the server, and this should allow you to set it and forget it for the future.
