Child Domains and pass-thru authentication

[emaybee]

I have a root domain (let's call it master.corp.com). It has 20,000 user accounts. I have a child domain called deptlab.master.corp.com that has printers and other resources that I'd like to share with the 20,000 users of master.corp.com. I have a workstation that is an object of deptlab.master.corp.com. When I attempt to login to deptlab.master.corp.com at the workstation using a account from master.corp.com, I get a unknown user or incorrect password error and I can only login directly to the root(parent) domain. What am I doing wrong and what can I do to fix this?

are you sure your selecting the correct domain from teh dropdown list?

and are you sure you set it up as a child domain and not as a seperate forest or domain tree?

stupid questions but normally thats what causes that

It's set up correctly as a child domain and I am trying to log in to the child domain not the parent.

well you cannot log into a child domain using an account from a different domain....you have to select the domain that user is a member of from the dropdown list in the ctrl+alt+del dialog

that is by design and wont change
