Happy New Year All.   I’m hoping to post more this year.  I hope 2018 brings all that you wish for. Have a great year! πŸ™‚


DFS : The Case Of The Missing Files

I’ve actually not used DFS all that much myself.   I’ve configured it a couple of times in a Lab Environment and it just worked, of course we all know things are different in the real world.

So I recently configured DFS across two servers Server-01 [names change to protect the identity of the innocent servers :-)] , Server-01 had approx. 300GB files to replicate across 3 shared folders. Server-02, the new server, empty of course. 

DFS Namespace was already installed, I added Replication on Server-01, so Server-02 was installed and configured as normal and replication started a few minutes after, awesome, so left it replicating over night and the following morning I checked.  That’s odd checked the file count between the servers there was a difference on the number of files returned. 

So I started investigating what was going on, at first I thought no replicating was happening at all, so I looked at the diagnostic report which suggested the staging area (a cache), was to small, I increased the size of it, at this point I wasn’t sure what I should change it to, the diagnostic report just reported it was to small, so I doubled it, from the default, 4096 to 8192 nothing happening to the file count. What was hopeful about this was if it was too small replication could stop, sounded like my issue.

When I found the dialogue to change the staging size, there was a link on that dialogue which explained staging and what was required to set the right size, you have to take the top 32 largest files and total them up and this is the figure that your staging should be set to, it only uses it if it required to and if it gets within predefined thresholds, the oldest files will be removed from the staging area.   The article provides a PowerShell script to total up the staging size:

More information regarding this can be found here :

After waiting awhile and checking, no new files appeared. πŸ™  However the staging error in the diagnostic report had gone, so I guess that was positive. I still had missing files, things weren’t making much sense at the this point, so I created a few test file on Server-01 and watched Server-02 to see if they appeared and they did, which meant replication was working, just not for all files.

So some files for whatever reason weren’t replicating, it turns out that DFS won’t replicate files that have been marked as Temporary, you have to check the files properties to see if the file has been marked as temporary and if you want that file to sync then you need to change its properties from “Temporary” to “Normal” and it will replicate. (More information about this can be found here,, I did this on a couple of test files and they replicated, so I ran it across the whole folder and this increased my replication count. Progress, but I still had missing files. πŸ™

Comparing folders and started to notice files with extensions, “tmp”, “bak” and starting with tidal (“~”).  This got me thinking, so if DFS doesn’t replicate files that are actually marked Temporary then files that use things, like “tmp”, “bak” and “~” may also be considered temporary files.   I wanted to prove this to myself, so I fired up two VM’s and configured DFS and ran some tests.

So now it was just a case of checking how many of these files that had the “bak”, “tmp” and “~” extensions and hoping that the total matched the missing number of files.  I did this using PowerShell to find the files and then I did a count on them and here’s the break down.
Server-01 : Folder-01, Total files : 673,791
Server-02 : Folder-01, Total Files : 669,049

Unaccounted for : 4,742

Files with “bak” extension : 4,483
Files with “~*” at the start  : 178
File with “tmp” and hidden extension  : 18
File with “tmp”  extension  : 63

Total : 4,742
Remaining files unaccounted for : 0
Server-01: Folder-02, Total Files : 909,084
Server-02: Folder-02, Total Files: 886,697
Unaccounted for: 22,387
Files with “bak” extension : 32
Files with “tmp” and hidden extension: 0
Files with “tmp” extension: 4
Files with “~” at the start: 22,351
Total: 22,387
Remaining files unaccounted for : 0
Problem solved, it was important to know that these weren’t production files not being replicated.

Enabling WordPress AutoUpdate – Windows Server

Looking at how to get WordPress running on Windows Server and allowing auto update to work.  This is what I did and it seems to work.   

I used the Web Platform Installer to install WordPress, I then downgraded it to WordPress 4.7, I just copied the files over the install.  So I could test the upgrade process.  When installing using the Web Platform you need to provide random generated key’s, I found this which generates random keys for you, but the Windows Installer doesn’t like $, which is a tad annoying. 

Hope this helps. Have fun πŸ™‚ 


Almost Scammed

My sister in-law purchase a new computer from what I deem a respectable retailer and to be clear, I think this is the still the case.

You can imagine my surprise and shock, when I received a call from her and she explained she was trying to install office and somehow managed to end up on a call with some guy who was telling her, it wasn’t the computer but there was a problem with the firewall and she had Trojan’s, which aren’t viruses, it’s different… 

This guy wanted to spend 40 – 45 mins on the computer to resolve the issue, of course he wanted Β£200. 

At this point I didn’t understand how this had happened.. How was it that she was on a call with some scammer that she called them. 

After checking over the computer and ensuring it was OK, it was and after asking some questions.  

She had purchased Office with the computer and off course wanted to install/activate it… she clicked on Cortana and asked Cortana to active, the default behavior for Cortana when it can’t answer directly, is of course to perform a Bing search, she then clicked what she thought was the correct link.

She had gone to the following site (I haven’t shared the URL as I don’t want to help them)  which looks fairly legit to anyone who hasn’t seen the genuine office activation page.

She typed in the key and of course it failed with an error. 


I haven’t been able to replicate the voice search performed by Cortana and get the same result as she can’t quite remember what she said. 

I have checked the source of the page and can’t see any evidence of the Product keys being harvested. 

Be safe out there fakes, it’s really easy to get caught out.
