Have a synology diskstation which is join to my domain and the domain administrator group has read and write permissions to all folders but will not accept any domain credentials to access the diskstatuion in file explorer (or when windows backup tries to access it).

This morning my PC couldn't start up. It worked normally yesterday but i did a hard shut down (holding the power button) and went to sleep. When i wanted to access the computer today it didn't start up, had BSOD (blue screen of death) right after the windows logo animation was finished. The error was; c000021a (Fatal System Error) The session manager initialization system process terminated unexpectedly with a status of 0xc000003a(0x00000000,0x00000000) .
I tried resetting to Factory setting (by the f8 method) but the screen that popped out offered no Repair option. I'm no tech guy so i'm asking for some help

Note; The PC is very old around 7 years and I've had recent BSOD issues but not of the same type, once I deleted a file I suspected caused it the issue was gone

New to exchange.  What I need to do is move all mailboxes from one site to another site, like a DR

Topology is:
Site A and Site B:  Each have Four servers, 2 have CAS Server, Hub Transport Server, Mailbox Server, Public Folder Server, the other 2 have CAS Server, Hub Transport Server, Mailbox Server

Have one DAG at each site and two CAS servers

From what I understand, I believe I'd want to move the active DB copy to another DAG member, switchover?  Looking at this link:  http://www.techrid.com/exchange-server-2010/moving-the-active-database-copy-to-another-dag-member-in-exchanger-server-2010/

Any advice or guidance would be appreciated.

Asus X555LA - how do I get into recovery mode - I can't seem to find it

Q1:
Does anyone scan Disaster recovery site, UAT, SIT & Development
sites?  

Q2:
For cold DR site that uses the same public & even the same
internal IP (as in ours) & same URL, I presume external it's not
possible as we'll hv duplicate IP.  One PCI-DSS doc suggests to
do VA & PT scans only for warm & hot sites: is this the common
practice?

Q3:
What about internal VA?  Do we do it on UAT, SIT & cold DR?

Q4:
Assuming cold site DR is powered down / isolated (ie not used
by even internal users), still worth doing external pentest &
internal VA?  When we apply fixes/patches/address vulnerabilities,
we propagate to our cold DR

Any best practice papers / authoritative links will be appreciated

I have a repository that is old and the data was copied to an external drive ready for archiving. What is the procedure to connect back to this data in the future?

Does windows server replica replicate from both sides from whatever side a change is made it replicate it to the other side??

Lost a server yesterday that had a RAID 1 Mirror configuration on it.  Could not boot to the mirrored drive and don't understand why not.   I thought that if you replaced the failed drive and tell it to rebuild the array. New to working with RAID.  Replaced the original drive and still could not get it to boot and rebuild.  Had to rebuild the server from scratch.  What did I do wrong?
