Changes to the Distributed File System (DFS) namespace are made on the domain controller with the PDC Emulator role. DFS root servers periodically request updated metadata from it. Inaccessibility of the PDC Emulator may result in incorrect operation of the DFS.
How to find you PDC

Recently during a DR test we spun up a file server that was protected using Microsoft Shared Cluster Services. The drives where mapped using a Physical Lun. Zerto protects this as long as you backup the Active Node of the cluster.
On Startup you need to change the VM Scsi mapping from Physical to None
Once booted , you should stop the Cluster Service and start is again with the /fixquorum flah
net start clussvc /fixquorum.
Now open the Cluster Manger and remove the Disks from the Server ( you will need to do this twice for each drive )
Once removed , stop the cluster service
bring Online the Disks in Computer manager.
If the disks come up as Raw , you will need to go back and perform a ReSync , then bring up again

Recently I was trying to add a Virtual Switch to a new Hyper V Server and I got an error similar to below
Although the Virtual Switch seemed to add ok , it was coming up with Errors in the Cluster Manager ( Status Unavailable )
The server was actually already added to the Failover Cluster Manager. And I noticed that the
“Microsoft vmm dhcpv4 server switch extension” filter was missing. This gets added to a Node on adding to cluster
Evicting the Hyper V host from the Cluster then deleting and re-adding the VSwitch Resolved this
So you are fully up-t0-date with Outlook however you are having issues with performance
Outlook display issues only affect 32-bit versions of Office. Normally, 32-bit applications can only access 2 GB of memory that all 32-bit apps share. Outlook appears to handle this limit poorly, making it unusable once available memory dips below what Outlook requires to run smoothly.
To see how much memory is available for Outlook, try the VMMap Sysinternals tool, which shows the private bytes or memory distributed for a process that cannot be shared. VMMap shows the bit version of Outlook, as well. For 32-bit Outlook, a number at 250,000 K or less is bad.
Use the following registry setting to prevent add-ins from using the extra memory available from LAA mode. Change the xx to 15 for Outlook 2013 or 16 for Outlook 2016:
HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\ReserveHighAddressRange DWORD Value ‘1’

Sometimes people need to document of capture a facebook profile page in a point in time. Due to the way facebook only loads the current data , a file and print does not work
The only easy way we have found to do this is the
If you press the Capture Icon once installed , then scroll down to the very bottom of the page ( you have to do this because the Page only loads whats on the screen ) , it saves the whole page as a single image
You can then print this Image to PDF which should divide it up into pages
