There was a domain called ABC.com (local domain), there were several users joined to this domain's AD. so they login to there windows machines using domain credentials.
Now those users were transferred together with there PCs, but without their Domain controller. So, they don't connect to AD server anymore to authenticate their login, but still use domain credentials to login.
Scenario is; this new PCs once connected to the ABC.com domain are needed to be connected to a new domain called XYZ.com (local domain). this new domain doesn't have any connection with ABC.com. I already added all the users details in to new AD (XYZ.com), but PCs are not yet joined.
I want to join these ABC.com previous domain PCs to XYZ.com domain simplest way and still want to retain the user data.
Example: John once worked for ABC.company so his login was;
user name: JohnD -----------} User Name: JohnDR (user loginname varies in the new AD, but same user)
Password : S3cr3t -----------} TO Password : n3ws3cr3t
Domain : ABC.com --------} Domain : XYZ.com
so, when John comes tomorrow morning and logs into XYZ.com and should see no difference. he should not see any difference at all, except he is log into XYZ.com domain. he should have his familiar desktop, all the apps, and docs.
How can I achieve this task?
One more thing;
I have setup a web proxy (cache). it's 192.168.1.1:8080. I need to enforce proxy settings in internet browsers (IE, firefox, chrome, safari) from the windows 2012 server GPO.
How Can I do this?
