Hi again,
About new Server .. I am trying to discuss with USA to get maximum possible control for you.
If we make it a member server instead of a Domain Controller you can have better control.
I do not have a AP Domain Controller in Australia and we have no problem so I think Thailand can be the same.
DNS might be a problem, I just need to know your requirements of DNS, if there is no special hosts inside your network that’s must have a URL then I think we are OK.
About Windows 10.
USA is only in the testing stage at present.
They allow us as network support to test but for general use yet.
32/64bit … I have not asked I just assume that 64 bit will be supported.
I will check.
