Some of the potential attacks involve putting a rogue router or DHCP server on your network. The best protection is to let the L2 switches filter the traffic. If a switch port goes to a workstation it probably should not send out packets that usually a DHCP server or a router would send. If you want such protection you should look at the protocols that the ...

It depends on whether you want them to do anything IP-aware. An ethernet frame is an ethernet frame is an ethernet frame, as Gertrude Stein didn't say; a good switch will repeat it based on MAC addresses without caring what the payload is, so if that's all your switches do - layer-2 stuff like VLANs and port-mirroring - you should be fine regardless.

Exchange 2007 and newer versions stop you from performing a domain rename. Since you say that you're ditching on-premise Exchange that's not a factor. That opens up the door for what I think would be a much easier process than any kind of creation of a new forest or domain: Complete your migration to Office 365 and remove Exchange from your SBS 2011 ...

There are a number of questions that arise from what you're describing.

This could easily turn into either opinion-based or "minimal understanding required" to be honest. Since this isn't a one size fits all thing. It will depend on your environment, options at your disposable, downtime allowed (which you stated), size of environment, IP network provisioning and overlap if any, and many other factors. However, given your ...

Is it possible migrate this all at one step with service downtime? If yes you can tar/untar. But better way is rsync mailbox on the fly, and at service downtime you do rsync again for update. look at mailqueue, this should be empty. smtp mustn't accept any mail at downtime. but usually you have different situation. mail queue keeps email that cannot send. ...

Dovecot have a handy tool called dsync (wiki) intended to syncronize two dovecot instances. Maildir hierarcy fron one server is replicated to another. Received, sent, spam, trash - everything is copied. The main advantage is that dsync can do an incremental and two-way replication. After the initial copying is done the next run copy the new/changed files ...

Attempts to decrypt the USMT.mig file with the recovery key found in the Computer Association -> Recovery Information obviously don't work, and with the original computer being reformatted, I'm quickly getting that feeling that any trace of the key needed to decrypt this file might be gone. Since the scan was done before this side-by-side ...
