How to Renew a SBS2011 Server Self-Signed Certificate


How many of you have ever let an Exchange certificate expire?


I did this morning. The situation: 7 users using a SBS2011 server. The 5 PCs in the office got a certificate warning, but after a “Cancel” their Outlook worked fine. The two users outside of the office who relied on HTTP to contact the Mail Server were dead in the water. I should mention that I used a self-signed   certificate on the server.




Since Exchange Server 2007, Microsoft incorporated the exchange management shell; a DOS like atmosphere that allows you to make any modification to the mail server. It’s syntax is very precise.

A quick Google search put me onto a pretty good article in position #3

The first two answers to the poster’s question mentioned the exchange management shell; starting with the “run get-exchange certificate” command. His answer stopped there except for a hard to understand syntax structure to use from there. Luckily, I read down to answer #4.

7 clicks of the mouse later, and my certificate was updated by two years to 2018. The 2 remote users Outlook came to life immediately. I did not even need to down the server or restart any services.

Here are the instructions given by Paul Marsden in the article:

1.) Start the Windows SBS2011 Standard Console
2.) Click on the Network icon in the top bar, then click the Connectivity tab
3.) Wait for the panel in the right to become active and then click on ‘Fix My Network’
4.) Let the wizard search for problems.
5.) One of the problems it should find is the expired certificate.
6.) Clear all the check-boxes except the certificate one and click Next
7.) This will then re-issue a new self signed certificate on the server.

Nine hours later, the Exchange Management Console still showed the certificates as expired. I had one Windows update to do, so I rebooted the server afterwards. Log back in and perform a quick check of the certificate valid to credentials:

Chrome and Unwanted Extensions

Google Chrome is a browser that millions of people use everyday. For work, at home, for play, it’s fast and easy.

Sometimes Google Chrome can get messy. Unwanted extensions are often installed by accident or by a malicious virus wanting to siphon your personal information. This is bad for both work and play. Here are some tips to take control and your Chrome browser functioning again. 

To get to your extensions, go to the top right of your chrome browser and click the menu icon.

Click settings. Settings

On the left side there is a list.

Click Extensions.


Now this is the part where you determine whether or not you have a suspicious looking extension. You can either disable it or completely remove it by clicking on the Trashcan icon on the right of the named extension. We recommend you choose the Trashcan just to stay on the safe side if you are unsure.

Some extensions like Ad-block Plus have an additional Options link below their descriptions as you can see in the picture above, which may give you more control of what that extension is capable of.

Always pay attention to what you download! Some apps and programs like to install additional features and/or other programs if you just zip through the install process without reading the steps and just hitting next until you get to the finish line. In this case, it’s okay to be the turtle in the race because safety is your priority here. Read through the install process carefully and make sure you check all the boxes that are ticked or not ticked to see what’s going on.

Resetting Chrome is the next step if you’re still experiencing a slow down. Programs like to play with things that isn’t necessarily theirs.

Some programs have the ability to alter or change how your browser operates. Anywhere from changing your homepage to changing how you search for things on the net. In this scenario, you may want to reset your Chrome browser back to it’s factory default settings. This is definitely strongly recommended versus the alternative of completely reinstalling the application altogether.

Start by going to the top right side and click the menu icon.

Click Settings.

SettingsOn the left side list, click Settings.

Hit the reset and you should be good to go! Test out Chrome and see how it works out for you now. If issues still persist, you’re probably going to have to contact a professional/tech support or run some anti-virus programs like Malwarebytes to solve your problems.

Hopefully this guide helps part of the fixing process. It definitely helped us out using these techniques in the field.
