We are running SCCM 2007 R3 with SP2, Background, I have a TS to install WIN7 that is advertised to a Deployment Collection, the deployment collection is poplulated by importing the computer information for a single computer and providing the clients MAC Address. Both in Production and Dev i have this issue. I PXE boot the client and it fails with the abort.com error, smspxe.log has the following: MAC=1C:C1:DE:AE:62:4D SMBIOS GUID=26662997-155F-11E0-B026-E580BF0C10E5 > Device not found in the database. I double checked i had the correct MAC, This happens in both prod and dev. I added another record for the client this time i only specified the SMBIOS id and added this to the same collection the Windows 7 deployment task sequence was advertised to, BOOM it worked and picks up the TS, the smspxe.log file now shows: MAC=1C:C1:DE:AE:62:4D SMBIOS GUID=26662997-155F-11E0-B026-E580BF0C10E5 > Device found in the database. MacCount=0 GuidCount=1 The interesting part is the MacCount=0 even though i have a record in the database for that MAC. It appears that SCCM is not matching the MAC's brought in by the import computer information wizzard. Or is their a patch im missing...

The plot thickens. The machine i was seeing this behavour on was an HP MINI 5103, today i recieved a IBM Thinkpad that we are keeping for the Win 7 project, added a record using the import a single computer wizard and specified the name and MAC address only adding it to the deployment collection. This machine PXE booted and found the advert and build successfully. MAC=00:24:7E:E0:CA:9C SMBIOS GUID=8173A350-054B-CB11-BA80-C38F12D3E6CD > Device found in the database. MacCount=1 GuidCount=0 This appears to be vender related or model specific and quite frustrating...

Hello - I think, you can start from the bleow article? http://blogs.technet.com/b/smsandmom/archive/2008/09/17/configmgr-2007-troubleshooting-pxe-service-point-issues-and-wds-service-not-starting.aspx Also, have you checked the resource is really available in DB using query ?

I'm guessing that you have a record in your database that has the same MAC address. PXE is picking up that record, and does not find an advertisement for it. You can query the MAC address table (System_MAC_Addres_ARR). You can then lookup the system record for it from the System_DISC table (based on the common ItemKey).

MAC=1C:C1:DE:AE:62:4D SMBIOS GUID=26662997-155F-11E0-B026-E580BF0C10E5 > Device found in the database. MacCount=1 GuidCount=2 After building it had duplicate GUID's , so deleted all trace i could find ran a query for both MAC and GUID, re imported just using the MAC and it worked, so looks like it was a stale record in the DB.
