I'm running GSS 2.5 from an XP Pro box and 24 Windows 7 clients. I'm using the Ghost Console with clients configured to use PC-DOS and the Realtek PCIe GBE NDIS2 driver. Apparently, several people in the community said that GSS 2.5 runs better on XP as opposed to on a Server 2008 R2 system that is also serving as an AD controller. I ran into problems with trying to add computers to the AD domain during ghosting. XP does work better.
When pushing the image from the console, both Unicast and Directed Broadcast work when I'm running trials. However Multicast does not work. It always times out and the error files says: Connection reset by server.
I'm aware that Multicasting has to be enabled on routers and switches. However, I don't manage any of our routing and switching equipment. We have a separate group for that. When I've done trials with just two clients using Unicast or Directed Broadcast, I get notified by our network people that the packet traffic is causing the VLAN core router to spike and go to 100% utilization.
I've been working with them to try to get Multicasting to work but it looks like there is still some tweaking to do because they tell me it's not just matter of enabling IGMP. It's seems like there's more involved than just doing an enable/disable thing.
Our network people use a series of Cisco routers and switches and I have no experience with that. What I can tell you is that the server goes to a Catalyst 3750 series and the units in the lab go through a WS-6504-E chassis. I'm guessing run by a Catalyst 6500 series switch. I don't know what other networking hardware is involved beyond that.
Does anyone have any experience with configuring Cisco hardware and their CGMP protocol that I can pass on to our network people so we can get multicast to work?
Thanks.
