Hi,
I have configured NAP DHCP using SCCM. I have Windows XP SP3 machines in my enviorment. From few days i'm facing issues with some client machines, most of them disconnects from network then again reconnects in 1-2 minutes. This happens at same time almost everyday. I've checked my DHCP lease expiration time, and evaluation time network access protection agent in SCCM. Both of them does not match with the time when machines disconnects from network. Also, i dont see anything in client logs. If this issue related with DHCP-NPS-SCCM or it this normal when clients updates its state to server?
