I have seen lot of queries regarding SCCM 2007: OSD deployment errors out within a few seconds after WinPE loads and then automatically reboots
As per my understanding there could be two possible reasons depending upon the error.
1. Network access account
winhttp; 80072ee2 means ERROR_INTERNET_TIMEOUT.
This account is needed during operating system deployment, because the computer receiving the operating system does not have a security context it can use to access content on the network.
See this article for how to configure network access account:

2. There could be problems with NIC drivers
