WDM5: Error when attempting to push our HAgent update

I'm getting an error when I try to push out a WES7HAgentUpgrade to a terminal:

Try 1:XC Failed: 1. [Error:Could not retrieve the list of all files and directory from Master Repository.] [WebDAV error:Failure to get directory tree from remote machine. HTTP Response Code: 404 Error Code: 404] Line#: 20 Cmd:XC WES7HAgentUpgrade\Temp\* C:\Temp\

Relevant System Details:

Brand new installation of WDM 5.0 on Windows Server 2008 (also new installation).

Terminal client is a C90LE7 Thin Client, version 9.03 (build 0827.4096), running WES7 version 6.01 (7601) SP1. I just recently flashed the image to the 0827 build via USB - it wouldn't connect to the WDM server until I did that. The C90LE7 unit is listed in the WDM Device Manager list.

I want to update the C90LE7 HAgent to the version 6.3.2.54 that came with WDM 5.0. The currently installed version of HAgent is 6.0.0.45.

Things I've Tried:

- I can go to localhost/.../Rapport directory and browse the directories and files there - no problem.

- I ran the Device Manager Diagnotic Report and everythign came up GREEN except for the following:
* FAIL: C:\Program Files (x86)\Wyse\WDM\Utilities\Database\DatabaseCredentialManager.exe (5.0.0.707) - File Doesn't Exist.
* FAIL: C:\Program Files (x86)\Wyse\WDM\Utilities\Database\HAConfigureUtility.exe (5.0.0.707) - File Doesn't Exist.
* FAIL: C:\Program Files (x86)\Wyse\WDM\Utilities\GUIExtractor\MgmtConsoleExtract.exe (5.0.0.707) - File Doesn't Exist.

Any ideas or suggestions? I'm lost.
