ArunVerry,
If you are using Ghosty Solution Suite 2.0, the issue is likely that there are no DOS (or Vista-compliant drivers if you are using GSS 2.5). If you have a valid support contract, I would advise upgrading to Ghost Solution Suite 3 (your support contract entitles you to a free upgrade). GSS3 uses WinPE 5.1, which will allow you to use Windows 8.x drivers for network support. Is that a possibility?
