Inject drivers into WDS boot image - Windows 7 x64

Im trying to inject drivers into boot.wim image using WAIK 3 for Windows 7 and Server 2008 R2. I'm working on Windows 7 x64 PC. After injecting network drivers into the image and publishing it to WDS server I am not able to see this image anymore on the list of boot images oon PXE boot. It shows that boot.wim is online using Windows Deployment Services.

I'm using following commands:

1. Run following command to clean up any previous wims/mounts

DISM /Cleanup-Wim

2.   To check image info:

Dism /Get-WimInfo /WimFile:C:\images\boot.wim

3.   To check mounted images:

dism /get-mountedwiminfo

1. Mount.Wim File on your local C Drive

dism /mount-wim /wimfile:c:\images\boot.wim /index:1 /Mountdir:c:\mount

1. Adding drivers command:

dism /image:c:\mount /add-driver /driver:c:\drivers\ /recurse

6.    Umouning image to wim file by running command:

dism /unmount-wim /mountdir:c:\mount\ /commit

I was trying different drivers, also x86 Windows 7 and drivers. I don't have any error message. We are running WDS on Server 2003 SP2(x86).
