Query regarding logging onto a different domain
Posted on 2009-03-29
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!
