One of our customers reported that they intermittently lost access to the Office Templates directory.
Sometimes it worked well, and sometimes “it was gone!”.
The environment was Windows 10, with Office 2016. The Office Templates were located on DFS shares (ie. the location was \\ALargecustomer\DFS\OurTemplates)
What could it possibly be???
It’s the Data Redirection feature that was introduced with Windows Vista, in November 2006.
Data Redirection – beginning with Windows Vista, standard users have restricted access to certain files, folders, and registry keys. When an application is trying to write to these locations, it gets redirected to somewhere else. Most of the time this is transparent to both users and application developers, but sometimes it is not and that lead to some very interesting results.

The customer had some issues running SAP Business One. The cause? SAP trying to write to a sub-directory under c:\Program Files (x86)\SAP .

The initial thought was “it’s another ‘SMB1 is disabled’ causing connectivity problems” problem.
Except it wasn’t.
The issue was that our customer reported that they could no longer connect to their NAS device.
With Windows 10 v1709, Microsoft disabled Guest Access. In their words:
Cause
This change in default behavior is by design and is recommended by Microsoft for security.
A malicious computer that impersonates a legitimate file server could allow users to connect as guests without their knowledge. Microsoft recommends that you do not change this default setting. If a remote device is configured to use guest credentials, an administrator should disable guest access to that remote device and configure correct authentication and authorization.
Windows and Windows Server have not enabled guest access or allowed remote users to connect as guest or anonymous users since Windows 2000. Only third-party remote devices might require guest access by default. Microsoft-provided operating systems do not.
For the small number of end users who will need to connect to a third-party NAS, we’ll probably manage it via exception.

Note that these tests are up to 9 years old. Use as a guide only.
What is here is what is here. I don’t have any other testing routes.

So Resilient File System (ReFS) has been for 6 years so it should be stable for use with a backup drive, right?
Nope:
“Because ReFS was designed not to fail, if failure does occur, there are no tools provided to repair it”
When it does fail, you might just end up with a 2TB backup drive that you cannot read.
🙁
I found one third-party tool which does work, ReclaiMe.
Seems to work well. If I need to pull data off this backup drive, I’ll purchase a license.
was something I wrote about 8 years ago, in Detecting inactive computers in your AD domain.
So it was time to update that*.
Get-ADComputer -Filter * -Properties Name, LastLogonTimeStamp | Select-Object -Property Name, CanonicalName, @{ n = "LastLogonDate"; e = { [datetime]::FromFileTime( $_.lastLogonTimestamp ) } } | Export-CSV -NoTypeInformation "C:\temp\lastlogontimestamp.csv"
will give you a handy list of computer name and the last time they were seen on the network#.
* The Quest product is no longer free.

I downloaded the latest Citrix Receiver product, and after the download, I was greeted with this:
It’s a quality product you have there Citrix.
I use VeraCrypt to create a encrypted hard drive. That way, if I lose the drive, the lucky finder won’t be able to read the data.
The steps are as follows:
