Hi, I've got SCCM 2007 SP1 installed on a non-routed test network. I have multiple domains on the network (2 domains from a child forest), and I'm able to successfully discover all Active Directory resources with AD Discovery. However, part of the eventual service offering that I'm testing will be accommodating workgroup users, who won't be discovered with AD Discovery. I've configured Network Discovery to search my subnet but it only ever seems to discover itself. There's no managed switch involved, nor a router -- it's essentially just a bunch of machines plugged in to the same switch. I have the "Type of Discovery" set to Topology, Client, and Client Operating System . On the client side, I've ensured that Network Discovery is on and that the resources are visible through the Network feature. Both the SCCM server and the targeted/hopefully-discoverable resources are visible through this window (Start Menu --> Network). I've also disabled the firewall on the clients to ensure that it's not a firewall issue. I've reviewed the following documents to no avail: How to Verify that Network Discovery is Complete (http://technet.microsoft.com/en-us/library/bb694173.aspx ) How To Configure Network Discovery (http://technet.microsoft.com/en-us/library/bb680347.aspx ) About Network Discovery (http://technet.microsoft.com/en-us/library/bb693986.aspx ) Windows Firewall Settings for Configuration Manager Clients (http://technet.microsoft.com/en-us/library/bb694088.aspx ) Discovery RUNS, but discovers nothing. Here's My Big Question! Is a router a requirement for subnet-based Network Discovery? Thanks! Nick

See if this helps: http://technet.microsoft.com/en-us/library/bb680962.aspx and this http://www.windows-noob.com/forums/index.php?/topic/1307-how-to-add-workgroup-clients-to-sccm-console/ Ther ewas apost here with detailed answers a while ago, however i get an error on the page, may be some one else can remember where it was.

If you are using Microsoft DHCP you can discover from that. See this: http://technet.microsoft.com/en-us/library/bb680764.aspx John Marcum | http://myitforum.com/cs2/blogs/jmarcum |

I've used the manual installation method with the SLP switch to get undiscovered clients to install, but if I go to a new customer and I say "I can discover all your devices", I need to be able to give them a level of comfort and confidence that I've gotten everything, not just the things I can see -- does that make sense? I appreciate the help!

I'm dealing with a totally static-IP address space, which is a requirement of my customers. It seems difficult for me to believe that if you have a switch, a server, and a bunch of devices, that you can't somehow discover them by broadcasting to the full switch and seeing what comes back. Efficient it's not, but effective, somewhat.

I don't think you will be able to discover those devices if there's no router nor DHCP. I haven't used network discovery in years because it's so messy but from what I recall it searches router ARP cache and DHCP so you will need one of those two in-place. I could be wrong though.
