Very slow network during WDS capture.

I'm trying to capture a Windows 8.1 x64 enterprise image from workstation and the network is going unbelievably slowly.

Details:

Windows 8.1 x64 guest

Workstation 10.0.1

Hardware version 10.0

2 vCPU. 1.5GB RAM

I have prepared a machine and sysprepped it, now capturing to a WDS server from a 8.1 x64 boot image:

When capturing the network stops working, I've managed no more than 15% in two hours, usually it doesn't even get started with the file transfer. A manual file copy to the server also fails with a Error 0x8007003B: An unexpected network error occurred. Pings are fine and I can login to the WDS server to see the image groups.

Switching the network card from 1000e to 1000 and the capture works fine. Has anyone else had this issue?
