V-79-57344-38264 - Unable to copy the virtual machine disk using the VMware VixDiskLib.

I faced this problem when doing backups from VMWare vSphere 4.1 with Backup Exec 2012 (media server is W2008 R2 Standard).

V-79-57344-38264 - Unable to copy the virtual machine disk using the VMware VixDiskLib.
VixDiskLib_Read() reported the error: The server refused connection

WARNING: "VMVCB::\\SVLASVCENTER01\VCGuestVm\(DC)LAS(DC)\vm\LXLASPDMR01\LXLASPDMR01\LXLASPDMR01.vmdk" is a corrupt file. This file cannot verify.

In my case was solution disabling NetDMA on media server with command: 

netsh int tcp set global netdma=disable

It decreased backup speed, but it just works. Hope this will help to people who have same problem.
