I have a new laptop that I intend to use both at home and at work. I happen to have a windows server setup with active directory at home, and I want to join the laptop to both domains. Is this possible?
Result: I've decided to join it to the work domain. I definitely need to be able to log in to windows using my account on that domain at times, while the home network is much simpler (mainly just file/print sharing, though there is more to it). I think I can manage at home by manually authenticating to the needed resources, and perhaps even script some of that away.
Short answer: no.
Since you're talking about work and home domains, I don't imagine you can set up a trust between them. OTOH, if you're even allowed to join a personal PC to the domain at work, maybe it's a small, informal company?
Workarounds: Join the home domain and just map individual resources and give your work credential, or maybe set up a VM on the laptop that's joined to the work domain.
Edit: while looking into this a bit more (because it's something a few of our remote users have asked about), I came across Globesoft MultiNetwork Manager, which says it can join one computer to two domains and switch easily between them.
Easiest way to handle this is to have your machine's "workgroup" be the same as the work domain... then have a UID on the local "workgroups" other machines the same as the uid for your work uid... then keep the passwords in sync... windows tries to 1st connect via the current uid/pwd (w/o the domain prefix), then if it doesn't authenticate, it prompts you... been years and years since I studied that, but been using it all along since winnt4
You can partition your hard drive and have the machine dual boot into separate OS's. One for home one for work. That is about the only way.
You can add the computer in multiple domains , 1.login as local user and join the computer with your 1st Domain. 2.Again log off from the domain and login with local admin --> join the 2nd domain. Now you can see the 2 domains in the drop down at the user login.
