Can a domain registrar take down a domain?
25/12/2015 9:47 am by frogger9 in Network & Servers

I am in the middle of a DMCA request, as I have found someone who is using some of my copyrighted content. The host is based in China, and is not responding to any requests (I have sent faxes, e-mails, and a letter).

Now, as far as I was aware, it is possible for a domain registrar (the domain is registered via Network Solution) to take down a domain by changing or destroying the name

Windows Server Manager stuck on 'Display will be complete when the server inventory has finished...'
25/12/2015 9:47 am by dcutting in Network & Servers

I cannot access Storage Pools in Server Manager because it seems that it's stuck on 'Display will be complete when the server inventory has finished...'. The little blue bar up top keeps running, so it's probably doing something. I have tried waiting but nothing happens. There are no event log records related to this either. I have also tried creating a storage pool using Powershell with no luc
