Next is make sure that you have a domain name registered, in our case it is widgets.com so all of the users setup on their server has an email such as email@example.com and they have a website at www.widgets.com. They have also made sure that they made the appropriate changes to their DNS for the widgets.com domain by creating an A (host) that contains their public static address IP.
I know it might sound basic but it is very common to hear from people that either don't have accounts or don't have an account with the appropriate security to allow remote access. Make sure that your account is part of the “Remote Web Users” security group.
Port Forwarding Through your Router
In order for the remote services to work correctly you must insure that your router’s firewall is configured to allow certain ports through. Look through the list below and ensure that those ports have been forwarded in your router.
Server 2012 R2 and Server 2016
On the newer servers you no longer have Self Signed Certificate option on your server so you will need to purchase and install an SSL Security Certificate form a 3rd party provider such as Godaddy.
If you have an IP address that is in part of or falls within any one in the list below you are looking at your internal private IP address.
For this example we are using an internal private IP address of 192.168.0 so if the small business server was assigned an IP address of 192.168.0.10 all seven of these rules would be forwarded to that address.
This certificate is created by the server when you install and configure it. It is what makes the “httpS” part of your remote address possible. Without this or with it incorrectly configured your Internet Explorer will first show you an error message.
Then even if you click on the “Continue to this website” option you will notice that the Header will glow red, Show you a certificate error and not allow you to remote onto your network.
Make sure that you install the security certificate on the computer that will be used to remote to the office. If you have from SBS 2003 or SBS 2011 you will need to install it manually. Just right click on it and select “install certificate” and place it in the “Trusted Root Certification Authorities” store. On SBS 2011 there is an installation file that does all this for you.
Connecting Remotely To Office
Now you are ready to connect to your remote office but still don’t know where you address is? Well more than likely if your work email is firstname.lastname@example.org then your remote address is https://remotee.widgets.com Open Internet Explorer and type your remote address and log in with the same user name and password that you use when you are logging in at your desktop at the office.
If you are unable to connect, review each of the step groups above and you will resolve it.
Setting up remote to the office
If you have a Small Business Server and you have never used remote you are in for a treat! When you or whom ever setup your Small Business Server were installing the server there was a point where information pertaining to how to access your server remotely was entered and the remote services were enabled.
*** For this example we will use a fictitious company named Widgets which has a web site named Widgets.com. ***
Static Public IP Address
In order for you to have access to remotely reach your files, emails or log onto the server or a desktop you need to have some pre-requisites on your network. One of the most basic is “Do you have a static public IP address”. If you don’t know what that is there is a pretty good chance you don’t. Call your ISP (Internet Service Provider) and not only verify that you have one but what is it’s address.
Now remember not to confuse this with your “Internal Private IP Address” that assigned by your DHCP server inside your network.
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private intranets: For further detail click HERE
