Query regarding logging onto a different domain

Hi All

I had a query regarding logging onto a different domain that I hope someone could help me with...

My domain is kam.com. We have emea.kam.com, us.kam.com and canada.kam.com

Each domain has a bunch of DC's and one GC. There is full trust between the domains, and network-wise full access between each as well.

User1 has an account located in the EMEA domain, but travels to the US.

When she logs onto a PC in the US, which DC does she authenticate to?

a) The local DC as defined by the subnet she is on within AD Sites and Services (i.e. a US DC)
b) An EMEA DC, since that is where her account is located
c) A US GC, since the GC would presumabely hold details of her account?

And if she changes her password, where is this replicated to first?

Any help appreciated!

Thanks - so I assume the partial information the GC holds about this user does not include the password? Otherwise, it would not need to refer back to a DC in the user's home domain?

That is correct - user passwords are not stored in the GC. A user must always be authenticated by a DC from it's originating domain.
