Network Name Could Not Be Found

Hi,

I just finished setting up windows deployment services and pxe on my server. I have created my deployment share and added all my drivers etc. But when i boot into Windows PE via pxe and attempt to connect to the Deployment Share, I get the error, "Invalid Credentials: The network name cannot be found." All the details i have entered are correct but it just doesn't seem to want to connect.

Thanks heaps
