I am about to implement DKIM signing on my domain, but couldn't find information about which one to start first: publish DNS or start signing keys.

Explains better:

Considering the time DNS takes to spread out, so:

• If I start signing first, people will see my signed messages before they can see my DNS entry.
• If i publish first, people will see my DNS entry but messages won't be signed.

Which one won't result in messages being rejected?

We have a ML6000 Dell tape library with a LTO-3 drive (part number KU838).

Can this drive support LTO-5 or LTO-6 via firmware upgrade? I could not find any information about this on Dell pages.

Is it even physically possible to a LTO-3 driver read or write LTO-4?

My WSUS installation is now using 100 Gb of disk.

Is there a way to reduce this usage? How can I, say, delete updates included in Service Packs?

I have a working IBM serveraid-8k .

My problem is that I need to read files from a HDD taken from another machine (not raid).

ServeRAID Manager sees the disk, but I found no way to access it from windows.

If I ask to create a new Logical Volume so I can see it on windows, will the controller erase the disk?

Thanks in advance.

UPDATE: To clarify the question, let me explain that, although Windows Disk Manager doesn't see the disk, the ServeRaid Manager (software to control the raid controller) sees it.

What I need to know (and haven't found yet) is how one makes the serveraid 8k controller expose a drive to Windows 2008 R2 without erasing all data already in the disk.
