Laptop will not connect

[LadySlinger]

I have a backup admin that recently received a new laptop. He changed the account name on his old laptop so that it can be recycled to a new person (i.e. x-laptop become y-laptop).

His new laptop was given the same name that the old laptop originally had (x-laptop).

Now when he attempts to connect to the domain his new laptop gives him error messages, saying that it cannot authenticate him to the domain because he is not trusted. We are on a DHCP network.

Does this have something to do with him having recycled the name x-laptop? I know he setup his new laptop before changing out the old laptop. I have a feeling that doing the setups out of order is confusing the heck out of the DC. If its something else, please let me know. He's certain that the issue is all on the server and that there is nothing to be done on his local machine.

Thanks

Before trying to add the new laptop to the domain, did he remove the existing laptop from the domain (ie demote it back to a workgroup). Try resetting the computer account and then try to add it to the domain.

thanks, I'll tell him to do that.

Another quick question -

the user also installed Mac OS X on his computer, so he's duel booting into the domain. Will this effect him being attached to the domain at all?
