Magic Packet sent out by SCCM
This drives my crazy!!, my SCCM/WDS sends out Magic Packets broadcasts every 300seconds, looking like this: Time received: 05/04/10 19:47:26 UDP Header: |-Source IP : 172.20.88.249 |-Destination IP : 172.20.88.249 |-Source Port : 9000 |-Destination Port : 4011 |-UDP Length : 282 |-UDP Checksum : 2887 MAC Address: FF FF FF FF FF FF Pasword: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 63 82 53 63 35 01 03 3C 09 50 58 45 43 6C 69 65 6E 74 61 11 00 94 6E 74 46 40 D1 7A 49 8C 46 54 63 A8 F0 06 FD FF Raw Data (274 bytes): 01 01 10 00 D7 30 00 00 00 00 00 00 AC 14 58 F9 00 00 00 00 00 00 00 00 00 00 00 00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 63 82 53 63 35 01 03 3C 09 50 58 45 43 6C 69 65 6E 74 61 11 00 94 6E 74 46 40 D1 7A 49 8C 46 54 63 A8 F0 06 FD FF The case is that WOL is NOT enabled at my site and the port configured for WOL is 9, no advertisement is masked with WOL. At the samt time (the time of the logfiles differs - but it appears exakt the same time, and this is just an example) this happens the pxecontrol.log says the following: ********************* $$<SMS_PXE_SERVICE_POINT><ti maj 04 21:52:42.471 2010 W.

the problem is that my Dell klients starts in like 1-3hrs Could you please clarify that? What does that mean? Are clients turned-on on a regular basis? That would be very unlikely (because of UDP Header: |-Source IP : 172.20.88.249 |-Destination IP : 172.20.88.249) and I've never seen clients been woken up by that check.

Yes, that is the exakt problem, and as SCCM is sending out Magic Packets Broadcasts of what I understand - and the clients are on some locations on the same subnet as the server and they are started randomly in 1 to 3 hrs. This is not the case on other location where the same Magic Packets also exist if running the scan on the DP but here are clients on another subnet and therefor not started - this is my guess?
