Ok, so everything seems to be working correctly. The PC picked up that there is an advertisement, but "pauses" at Pendeing request ID: 423 and the appove text is of course administrator needs to approve...No erros, just stalled. No abortpxe error or anything... Is there a place in sccm 2007 to go and approve these requests, or any answer would be great

No, you do not have to approve anything in ConfigMgr. However, PXE boot is being serviced by WDS so if you set up WDS to require approvals, then you'll have to go into WDS and perform the approval. There are a lot of differing opinions about whether you should configure WDS after installation or not. I for one have never had an issue leaving WDS in its default, uncofngiured state and allowing ConfigMgr to manage it.Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys

I had once this situation, that client booting from PXE tried to contact the SCCM OSD server for a long time. The reason was, that I had disabled previously x64 boot image from console, and the computer was x64 based. So you may want to check, wherever both architecture boot images are enabled for PXE.
