For a better user experience than my old work XP laptop, I built a Windows 7 64bit Professional with Office 2010 as my home machine. However, I cannot connect to my work domain and I am being told "we don't support private machines - fix it yourself." Fine! I am guessing it's because my new machine has a new SID which is not associated with my credentials and so is not passing authentication. If NewSID still worked I could just copy my old work SID over and solve the issue (maybe) but as this does not work with Win7x64 that's not an option. I could make a clone and then upgrade but this would mean a complete rebuild with all the ____ I am trying to avoid with a clean build. So how can I replicate my SID from my old machine to my new? Any ideas? I am a UNIX guy so please excuse me asking if you are really specific with your answers. I like Windows 7 and want to get under the hood but for now treat me as a newbie please. Thanks

Its not really about the SID. A trust relationship has to be established between the computer and the domain. There is no process that I know of that you can take advantage of in regards to moving one SID to another computer. To connect to your work domain, an administrator of that domain simply needs to create a computer account for your computer and have the computer join the domain. Your computer, while on the corporate network, would simply be configured with an IP on the subnet and the DNS settings would need to point to the internal corporate DNS servers. That is pretty much it. There is no way around that for domain membership. Now, you can plug your "personal" computer into the corporate network (assuming that there are no policies preventing you from doing so) and use domain resources. However, if your computer is not joined and you do not log on to the domain, any resource you access will result in prompting you for credentials. You would then simply type in your domain user id and password. Visit: anITKB.com, an IT Knowledge Base.
