There have been many articles on various forums on how to setup mcrosoft active directory domain services. I am a bit new to the field, so please bear with my ignorance. I have a very basic query whose answer i am not able to find. I have an office of 20 people where i would like to deploy AD Domain services to have a better control. i want to know how should i set my network PHYSICALLY. I have a router supplied by my internet provider. Where exactly should i put my server? Can i plug my server anyhere in the network and connect the users through domain, or the main internet wire should plug into the server first and the users in turn be connected to the server. enter image description here I hope i am clear. Should internet ‘flow’ from the server which has AD to users, or i can put the serverver anywhere in the topology.
In a small size network like yours, 1 server should be enough. It should be somewhere behind the router. Plugging it into the switch is fine as it will have a internal address.
You will need DNS on your server which will install when you promote to a DC. All of your computers need to look at your server for DNS. Your Server's DNS should have a forwarder to your ISP DNS or to a public DNS. It doesn't matter if you server or your router does DHCP so long as it gives out the server Internal IP for DNS.
What would I do:
I would plug your ISP into the Router, Your Router into your Switch, and all computers + server into the Switch.
You can place your server anywhere in the topology. It is not necessary for all user traffic to the internet to be routed through the server.
With small-scale deployments (less than 25 Users) I typically just put the server on the same switch and subnet as the users.

I am using (airtel xstream fiber) connection and trying to do port forwarding. I forwarded port 3000 of wan and direct it to my system ip address 192.168.1.2 on port 3001.
Node server is running on my system on port 3001. And I can access my hello world website locally using 192.168.1.2:3001. But when I am trying to access using public ip, it show this error code "ERR_CONNECTION_TIMED_OUT".
Also, I found my router port 3001 is open using online port checking tool/website.
So, Can anyone please tell what could be reason behind this ? Is this the problem with windows.
You first need to check what ports are open by your ISP. If your ISP is giving you a local ip at the router. Basically, creating a ppp connection. It may be using a cg nat. In that case you need to buy a static ip, without that none of the traffic will be Directed to your router. Let me know if you find something, I'm currently looking to get xstream airtel as well.
No there is no need for static IP to be access server remotely. As of now, What I see is airtel allocates new ip every 24 hr or when router got disconnected. To access your server remotely you can do two things. First one is more secured.
Change Primary IP adress of your airtel router and use Portforwarding so that its port 80 will be free for you.
Enable DMZ and point it to your local server IP. [192.168.X.X]. In this case all of your ports of the device are exposed to internet. If you want to be secure. Make sure add another router between server and airtel router and enable port forwarding.
But in this case there is a catch, When you try to access your local website using public ip (which you can see on google search) it will redirect you to airtel router panel. But when you try to access it using other device (not server otherwise server will get disconnected) connected to internet using other network(other that your current airtel router like JIO sim, Airtel Sim, etc), It will work excellently.
To get rid of dynamic ip use no-ip services. Its website will help you more. Basically, It is dynamic dns server where you will get free domain. That will get update regularly while its service running on your system. To use other dns provider service like godaddy you must need an static ip.
Guidance on how to connect to SQL Server 2012 needed.
I am on Windows 10 Home Edition
I have set up SQL Server Express to allow remote connections on my database machine to serve up data to three client machines.
Firewall has been set for ports - check
Allowed mixed mode logins - check
Setup IPs through SQL Configuration Manager - check
The server is something like 192.168.1.40,1433 and I can login successfully through SQL Server Express on my client machines. I had a long LAN cable running along the floor which is not optimal. So, I went to the store and bought a router so that I could connect wirelessly but have limited experience in networking.
After, installation of the router I can no longer connect to SQL Server. This makes sense since there is another piece of hardware in the chain.
After doing an IP config on the command line I see that the IPV4 address has changed. I assume I am not picking up the private IP address of the router rather than the modem that I was initially connected to.
Should I be port forwarding?
What are my options?
I explored what I thought may be reasonable leads to get this working.
First, I tried to create a virtual server (I also assume this is how to port forward on my particular router). I didn't really know what to put in five fields that were given other than server name and Protocol TCP or if I was on the right track at all.
The other three fields consist of:
External Port, Internal IP, and Internal Port
If this is a reasonable solution can you let me know what to put in these fields and any changes to the SQL Server configuration or firewall might be?
Should I VPN ?
After exploring this option on google I also notice people saying, "set up a VPN is the correct way to go." However, I don't really know how to do this. The only VPNs I know of are external VPN providers. It seems that I would be setting up a VPN server if I am not corrected(maybe on the server computer) and connecting via my client machines.
Any clarification or direction would be greatly appreciated. I am sure I have missed the mark on many things here but still would like to make ground.
I would like to create a local wireless without internet.
I would like to have the possibility to connect 50 clients and access to a website using a domain name.
That means, I need a DNS and DHCP.
I sreach on internet an I found a way to achieve that but not totally and i am not sure if it will work and if it is the best way to achieve that.
I can maybe have a mini PC (server) with ad hoc network and have the client to connect on the server but:
Will it be possible on a connection to assign a ip to the client and set a DNS server ip on the client as the same ip of the server.
I found mini PCs but how can I know if the PC will handle a lot of client ? Which network card to choose ?
I think also that a router and configure DHCP on it to distribute the IPs but I would like to have one box ready object as a mini PC.
I need an advice on the best way to go with what i want to achieve and materials i need to buy and good references.
For a linux domain controler you will need to install bind to host your own DNS. It's a little involved to set up, but necessary if your network doesn't have a DNS server. If you're using a windows domain controller you will need a server OS (expensive). If you only have 50 clients the DNS resources needed will be small and you could run bind from any old box, even a Raspberry Pi. You will also need a host machine for the "website" a.k.a. an intranet. This can be the same machine as your DNS server, but can be any computer on the network. When all is done you will have your router configured with the IP of your local DNS server. The DNS server will point your local domain to whatever box hosts the intranet website.
Pretext: There is a ABC company providing Virtual Private Server for $xx, which includes features like blah1, blah2, blah3 and 1 dedicated IP address.
I have my home FiOS internet connection.
I have serverA, serverB, serverC running at my home.
Let's assume ServerA is a web server.
Scenario 1:
To access this web serve from outside my LAN, I would type "myDynamicIPAddress", we are assuming it still has the same lease token, and get access to my website successfully.
Scenario 2:
I am at my school/work(I work at a corporate office). I would type "myDynamicIPAddress" to access my web server. Since my IP address is dynamic/residential, it is blocked(All residential IP are blocked by default, to reduce the chance of them getting infected and sending out spams).
My question:
Is there any way to connect my home network to the VPS that I purchased(the one with dedicated IP, remember?), so that I can use that dedicated IP address to connect to my web server from my school/work where residential IP address are blocked(this also means no Dyndns.com/no-ip.com).
I hope I explained my question correctly and I posted it in the right section.
Thank You in advance.
EDIT1: I found this one question, but I want to do the exact opposite of what the user in this question is asking for.
https://superuser.com/questions/498529/is-it-possible-to-use-a-static-ip-assigned-by-my-isp-for-an-offsite-web-server-o
The answer is the same as the other question, for the same reasons. The IP address is routed to the owning network prefix so it can't be used at a different location without changing the Internet routing tables to point the overall prefix to route to a different place. Since you don't own the network prefix, you can't do that.
I published a web application to one of app servers. Now, if I am connected within my company network (no login require), I can access the web site no problem. Now, if I am connected from outside of the network over VPN, I can't access the website (Getting page not found appears). Do I need to configure IIS on the app server for allowing the connection over VPN?
Thanks for your time.
It sounds like you do not have your firewall/router configured correctly to allow traffic from external sources. When your connected via VPN it is like you are connected to the internal network. Without the VPN you need to make sure it is routed correctly and visible through your firewall. Can you ping the IP that you are trying to get to?
Do you get DNS resolution when you connect over the VPN? If you are trying to hit an internal machine name address, you might try changing to the IP address of the machine.
