Event ID 4101

Hello,

I have a WDS server working for all of my Windows 7 and 8.1 machines. 

Server 2012 R2 and WDS and no DHCP on the same machine.

I use IP helper on the VLAN's so there are no options 66 and 67 on the DHCP ranges. 

I am getting the below error for a Capture Image I am trying to add new. Existing images working fine.

Log Name:      Microsoft-Windows-Deployment-Services-Diagnostics/Admin
Source:        Microsoft-Windows-Deployment-Services-Diagnostics
Date:          9/25/2015 4:38:57 PM
Event ID:      4101
Task Category: None
Level:         Error
Keywords:      (4)
User:          SYSTEM
Computer:      Servername.domain
Description:
The Following Client failed TFTP Download: 

Client IP: 10.66.10.20
Filename: \Boot\x64\Images\Windows10Capture.wim
ErrorCode: 1460
File Size: 258405544
Client Port: 9957
Server Port: 64851
Variable Window: true

The Image starts downloading and it fails with the above event ID on the server and below error codes.

I have a TFTP Maximum Block Size of 8192 on the server, the same value works for all of the other images/machines. The Variable Windows Extension is ticked on the WDS as well.

Tried reducing the TFTP Maximum Block Size to 1024 and tested with same issue.

Also tried to load the BCD file and edit the ramdisktftpblocksize to 1024, which didn't help either.

Is anyone else having issues ? 

The device is a Acer Aspire R13 if it makes any difference.
