Hello all, I have some question on OSD that I'm hoping will be answered: 1. If I want to advertise a OSD TS to known and unknown computers, I should be able to do this as long as I set the ADV to be not mandatory, set the TS to run only on specified platforms (we don't have any x64 Windows Vista) and also set a password to PXE boot. Any pitfalls in doing this? 2. We currently use MDT, I have integrated MDT into SCCM, PSP has been installed on a new server. I would like to use MDT once in a while to image, this should be possible as long as I change the WDS provider order, correct? I know that most articles say don't configure WDS after PSP has been installed, but also have seen once that say it's OK to configure WDS after PSP install. 3. We tested multicast using SCCM OSD, got horrible speeds when testing unless it was on the same switch. Changed the apBlockSize in WDS and that seemed to help, although the CPU is maxed out when imaging with this change. The SCCM server is a vmware VM and the network speed shown is 10Gbps, and as far as I know the networking gear is all cisco. Any ideas on how to improve the speed without the registry change? I tried setting the "transfer rate" to 1gbps, but that didn't help unless I made the registry change. 4. When running "use toolkit package" I see that it gets downloaded multiple times, shouldn't it cache the content? I tried "persist content in the client cache", but that didn't seem to help. 5. Which packages used by the TS need to have the "multicast" attribute set? I'm assuming the actuall image and anything that runs in PE, so MDT toolkit should have the "allow this package to be transferred via multicast", correct?
