Hi Carol,

I don't think this is a significant techncial change and here is why.

Would knowing the correct behavior change an administrator’s decision about whether to use auto-site assignment when a computer has multiple addresses?

This would require that the site boundaries were IP boundaries and would require that a potential client was connected and had two IP's and that one of the IP's was outside of the boundaries.

From what I see with customers they usually don't use the /AUTO switch with client installations using client push, GPO, batch files, so on. They put in the site code, and why not. Assuming they did use the /AUTO switch it would still mean that there was a 50% chance on the first try they are going to find the site code. And how often will a client installation take place where a potential client is using more than one IP? Over VPN? a wireless network? Those don't describe most client installations these days, it is done as part of the OSD process, through a package (can't get that if you are outside the sites boundaries), or through the console. So it is possible if they push the client from the console or with client push. If they are using the client push there is a 50% chance they are going to get it tomorrow, if it is done by right clicking on a collection it still tries to find the site, it may find it before it gives up, 25 hours later, I forget how long it tries.

So the odds are pretty high that it will get the client.

Would this information provide the missing information about why auto-site assignment failed?

Yes, it would. I have seen this questions come up a few times and I have told customers the first bound NIC rule.

Regards,

Anthony

As I was the customer reporting this topic, I just want to let you know that we are actually trying to get a DCR for this because as a result, about 5% of our clients are unmanaged and we have to use another product to patch these clients.
