I have one AD account that I, at different times, want to use at two phyiscal computers (referred to as computer1 & computer2). To be clear about the time aspeact, I never want to be logged in on both computers at a certain time.
- In Computer1 Windows is installed and joined to the domain. I have permission to do this myself
- Software: Windows7 x64 SP1
- One constraint to my solution is that I will have to use the same computer name.
Now to the problem. On computer2 I install Windows and added computer2 to the domain as well. It worked well, but then when I logged out and tried to log in on computer1 I got a error message:
This computer is unable to establish a trust relationship with the server
The issue was quickly solved by removing computer1 from the domain and re-joining it again using my local admin account. However, I don´t want to do that each time I switch computer.
Thoughts and Questions
From what I´ve read on the internet one way to solve the issue might be to unplug the network adapter and login to disable Windows from checking with the AD server, and then re-connect the network cable again. Haven´t verified this solution.
I´ve also read about SIDs in various forms. One is something called "computer SID" or "machine SID" which seems to be string that is used to represent/identify the actual computer associated with an AD account. Just a theory, but if I can synchronize those SIDs between the two computers then would I be able to use them as I plan?
Are there any risk involved with using one AD account at two different computers? I don´t use the file share pushed out by the admins. But perhaps there are other things that I use in the background that may cause trouble?
I´m using Windows7, and I guess the functionality to remotely administrate my computer is built into the OS by now (compared to WinXP). What kind of reports are the admins able to get from me? Can they for example get a list of all the applications I´ve installed?
Even though it isn´t needed, I stil wonder what will happens if I log in on both computers at the same time?
And the final question, is it possible to solve my problem?
