Please note that the WIN Server 2003 version is not a vergin, (which includes some hotfixes, and when I ran N-lite it removed these Hotfixes before Sliptreaming.) ----when I run the CD and boot the computer, everything works fine till the installation started, then I received an error message of: Stop:C0000139 {Entry point not found} This procedure entrypoint I_RpcSNCHOption could not be located in the dynamic link library RPCRT4.dll Thanks, S.
