Purely windows questions What are FSMO roles and which one is forest wide and which one is domain wide? which one of FSMO role is least important, and we can run the system for a week without that? Replication commands, how to force replication, a DC in a replication is turned off for 180 days and it’s not replicating anymore, how to fix it? How to update the time source in a workgroup computer, how to do that in a domain? I said PDC is doing that in the domain and time pool in the workgroup can update the time in workgroup. He was after the time source setting in the workgroup. Difference between Shared permission and NTFS permissions We don’t have access to the console of a VM/PC and RDC is not working, walk through the process of troubleshooting. He said telnet is not working, what you do? How to connect remotely to the PC with remote tools? If remote registry works where you look into the RDC issue? Customer reported VM is slow, how to troubleshoot that? What you do that with performance monitor? Iterative and recursive query differences? How to schedule performance monitor? Through windows task scheduler BSD come up, how to troubleshoot that? Windbg debugging, how you debug memory.dmp file, what command you know for that. There are a bunch of 2012 servers in the AD how to apply a policy to them? If you answer we put them all in an OU and apply the policy he will ask you imagine they are all around in the AD not in one OU, how to do that? Now, we created a new server and added that server into the group of 2012 servers but it’s not getting the GP, how to troubleshoot that? He said that it’s getting all other policies and we have forced the policy as well(gpupdate /force), I said about inheritances, he said that’s not disabled, I was stuck in this question. What was one of the improvements for the user or system you have done? Tell me about something bad which happened to you? How do you keep your self up to date with technology? Tell me about resources ( I mentioned CBT Nuggets, Guru, workshops, youtube and so on)
