Can someone explain what would/could happen in the following scenario?
Multiple domain controllers; 1 PDC at a colo and 2+ DCs at separate sites.
If a use's account is modified in Active directory on Domain Controller A at one site and then the same change is made on Domain Controller B at another site before DC-A has a chance to replicate, will this cause a problem? An example of possible changes would be password reset, profile path change or security group member change.
Are the implications different if the change is made on the PDC then on local DC or vise versa?
I'm trying to figure out what possible issues are created if say a client calls and asks to have a change made, then the call is dropped and the client decides to call in again and gets a different tech and both techs make a change but on different DCs with in a few minutes of each other.
Hopefully this is enough information, but if not please let me know and I can add some more details.
