My company wants to create two virtual 2008 R2 servers on laptops in case of emergency. This way we can run a bare bones network with a DC and file server until we bring the main network back online. My question is that if I create a new DC with DNS obviously and then shut down the virtual machine until several days before a storm is likely to hit us will AD ans DNS continue to try and replicate to that machine even though it is not on? Also, will the PDC put that DC into tombstone state if is unable to successfully replicate to it for a certain period of time. I would like to be able to set this emergency DC up, so I can use my NTFS permissions on the file server, but I do not want to cause more problems in the meantime. Any help and advice would be much appreciated with this.
