Many internal companies use Newsletter services such as Mailchimp to email out internal newsletters. The From Address of this is usually an internal email address which means it will get rejected by the anti spoofing policy

Option 1

In Mimecast Administration Panel go to : 

Administration -> Gateway -> Policies -> Anti Spoofing SPF based Bypass

  1. Add the following Policy, this will only whitelist IP’s in your SPF Record,  so putting servers.mcsv.net will not work , you will also have to put “ip4:205.201.128.0/20 ip4:198.2.128.0/18 ip4:148.105.0.0/16” in your SPF record. If your SPF is over 255 characters : try option 2

 

Option 2

Administration -> Gateway -> Policies -> Anti Spoofing

Add the policy below , you can get a list of IP’s Mailchimp user here

Recently I was trying to add a Virtual Switch to a new Hyper V Server and I got an error similar to below

Image result for adding ports to the switch failed hyper v

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

  1. The first thing Microsoft 365 support will do it recreate your profile, and also recreate your OST , so make sure you have done this
  2. Next they will get you to run this :  Microsoft Support and Recovery Assistant for Office 365 (also known as ‘SaRA’). If will give you a list of problems you can work towards resolving
  3. Make sure you upgrade to 64bit Version of Office

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’

Recently had a user receive an email that got past multi Spam protection. The issue was the sender had actually been hacked and they were using his email service to spam all his contacts with the below:

I was recently trying to Upgrade the AADconnect server to stop the high 100% CPU issues

After running the MSI . then running AzureADConnect.exe , the upgrade came up with the error

Unable to upgrade the LocalDB Sql Express database Running

I went to the event log and found the error :

Error installing msi package ‘SqlLocalDB.msi’. Full log is available at ‘C:\ProgramData\AADConnect\SqlLocalDB_Upgrade-20180813-094321.log’.

I checked through the Log and there seemed to be lots of 1603 errors

I ran the SQL Setup ( C:\Program Files\Microsoft Azure Active Directory Connect\SetupFiles\SqlLocalDB.msi ) manually and it asked if I wanted to upgrade my LocalDB from 2008 to 2012 which I said yes to 


The installer then came up with the error SQL Server 2012 Express LocalDB

Could not open key: UNKNOWN\Components\. Verify that you have sufficient access to that key, or contact your support personnel.

I ran through the workaround 1 from this guide

https://blogs.msdn.microsoft.com/sqlserverfaq/2010/03/30/sql-server-2008-setup-fails-to-install-with-error-1402/

And then the SqlLocalDB.msi finished successfully , I was then able to run through the AzureADConnect.exe upgrade

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 use this Chrome Add In 

https://chrome.google.com/webstore/detail/full-page-screen-capture/fdpohaocaechififmbbbbbknoalclacl?hl=en

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

You need to be listing on port 80 then redirect to https:// 443 , then after you can redirect non to www ( or the other way around ) for SEO

Default nginx.conf location is in /etc/nginx/

server {
#Listen on http first and redirect to https://
listen 80 default_server;
listen [::]:80 default_server;
server_name www.domain.com domain.com;
return 301 https://domain.com$request_uri;
}
server {
#Listen on HTTPS:// then redirect non www to www
listen 443 ssl;
server_name www.domain.com;
ssl_certificate /etc/pki/nginx/star2018.pem;
ssl_certificate_key /etc/pki/nginx/wildcard.key;
root /usr/share/nginx/html;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";
# Set client body size to 10M.
client_max_body_size 10M;
if ($host = 'domain.com') {return 301 https://www.domain.com$request_uri;}
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location / {
        index index.php;
        try_files $uri /index.php$is_args$args;

}

error_page 404 /404.html;
    location = /40x.html {
}

error_page 500 502 503 504 /50x.html;
    location = /50x.html {
}
location ~ \.php$ {

        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

         fastcgi_index index.php;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;


 }

After saving this you need to restart nginx

sudo service nginx restart

Then use : https://hstspreload.org to test

Recently on booting a Xseries IBM x3650 server the following error was diplayed on the bios and the server would not start

Fatal Error : Controller monitor Failed. Controller now started

This is an error on the onBoard raid controller. Reseating the memory and unplugging and plugging in the battery did not help.

In the end we had to swap the whole mainboard out. The metadata for the Raid drives is stored on disk so no data was lost

After upgrading to the lastest wordpress version I was greeted with a chance to install Gutenberg Plugin

My first instinct of using this was it felt a lot like Squarespace! As a WordPress developer I have been moving some customers across to Squarespace because of the ease of design and use, not to mention its fully hosted , and updated and even come with a free domain name.

The whole editor is so much easier to write with and less technical, you can do so much now like insert tables without a plugin , Titling is now much easier to define. It feels like a huge step in the right direction
