Hello,
Since 3 weeks we have an issue where the clients are releasing there IP address during OS Deployment, and mostly during downloading the .wim file or during the applying image. (If you try for 4 or 5 times it sometime passes and will be successfully deployed)
The DHCP lease times are set to 24H. I ran a F8 and then i did a ping to the distribution server during the download / applying. What we see is that after and X moment (within 20min still in WinPE) the NIC looses its IP address and gets a 169.x.x.x.x.x address.
If this happens during Applying Images (before its complete) and you manually do a ipconfig/release and /renew it successfully continues. If it happens during download it off course stops instantly.
We tested it on several routers and different configurations. All with the same result a failing OSD. We ran SCCM2012 SP1. The WinPE has the latest NIC drivers.
Greetings
