Azure Dns Zone not Resolving on Virtual Machine - azure

On Azure (through portal)
Created Virtual Machine with a Static IP, data disk, and opened ports
Then remote desktop - Install IIS and FTP, ports opened in firewall
(can successfully connect via ftp client)
Created a Public Load Balancer with a Static IP with Probes and Rules
(can connect with ftp client through load balancer ip address fine)
(if I enter ip address of load balancer in browser I can view the default iis website fine) (at moment there is only one vm in virtual machine set)
Added a couple of websites in IIS, one a .net app, and the other with just some hello world .html files to test connectivity via domain name. I set bindings to host name for websites with and without www. and IP address set to all (*). restarted websites.
Created a couple of Azure DNZ Zones with A Records pointing to the Load Balancer IP address. Changed name servers on domain register to point to the azure dns servers.
However, this is where it stops. A browser cannot get to either website and I get a '500' error. dns propogation check tools verify that the nameservers are reaching azure for domain names.
There must be something really basic I am missing (???) It is as if DNS resolution is stopping at the virtual machines. Any suggestions.

If you are Configuring multiple websites in a IIS of VM and also you want to map them for different domain name, then you need to Configure Host Header for all websites in IIS (Please find below links for this) and also need to update same A Record for all your websites at you Domain provider setting.
This will work if you have separate Domain Names registered else it will not work.
Without domain name you can deploy websites on different ports in IIS and then configure custom domain in Azure Load Balancer NAT rules.

This was my fault in some missing hyphens in the zone record. The other .net website was throwing 500 errors sometimes instead of error-name-not_resolved from incomplete nameserver propogation and incomplete .net configuration for the website on VM
The host headers were set correctly including www.xxx.com and .xxx.com variants for both port 80 and port 443, and I did have the 'A' records with both # and www variants in the zone set to the IP of the load balancer correctly.
For anyone else with these issues, when checking for localhost connectivity test on your virtual machine (assuming you are hosting multiple sites), remember to add a virtual directory in IIS manager pointing to the file location along with an alias.
While a learning curve, the whole infrastructure of Azure is quite amazing! Impressed.

Website in IIS locally and Domain Name bought from GoDaddy - What Next

I have been at this since last couple of weeks. After tiring efforts leading to nowhere, I am posting here.
I have a Website built and hosted in IIS locally. I just bought domain name from GoDaddy. I have my computer's public IP where the website in IIS is present. What are my next steps so that I can keep my computer as server and link with domain name? So that website is accessible publicly through domain name.
I saw a lot of posts with Web Hosting in Azure or other places, do I HAVE TO buy and host to make my site public?
I am a novice website builder and have very limited knowledge about this.
first you need make sure your sever is secured, only open necessary ports
go to another computer, in browser input public ip to see if you can open your webpage
then in Godaddy you can add A record for your domain, to point your domain to your public IP, refer to this GoDaddy document: https://ca.godaddy.com/help/add-an-a-record-19238
If you are not comfortable or don't resource to do these, I suggest you host on Azure or other cloud providers
You could host your application in either Azure VM or your local machine. After all, Could VM should be more convenient because you don't need spend a lot of time to handle network issue and you don't need physical space.
When you decide to host your application locally, you have to ensure your are using windows server OS, otherwise, you have 10 concurrent request limit.
Access the application via domain is quite simple.
You need to enable port like 80 in windows firewall.Promise your server are in DMZ and can be accessed externally
Create IIS binding header with null domain and your public address
Try to access your website via your public IP address
Point godday domain to your public IP address
Add your domain to your Site's binding host header->host name field
If you decide to host your application in IAAS like Azure VM, then you have to create inbound rule for your port number and allow port in windows firewall. You also have to point your godday domain to your cloud VM's public IP address and create IIS binding with your domain. Finally, you should be able to access your website.

How to add subdomain pointing to other website on same server

I have 2 websites I want to run on one virtual machine.
One is a NodeJS server, the other an Nginx server.
The main website website.example points to the NodeJS server.
Now I want a subdomain like shop.website.example to point to the Nginx server.
The virtual machine is in Azure.
I've read that it's not possible to link a subdomain to a specific port, so that's already not possible.
Would it be possible to have different IP's that go to the website, and would route to the right server based on the IP that is being used?
As far as I know, if you want to access the two websites in the same Azure VM, It's possible to use two DNS records to map to your Azure VM.
First of all, the two websites should listen on different ports. Then you can use A record to map the domain name website.example to the Azure VM public IP address. A CNAME record maps the subdomain name shop.website.example to the Azure VM FQDN. You should bind the different hostname of the websites with different ports on the Azure VM.
Also, make sure you could access the website outside of Azure. You could check the NSG rule or local firewall or website is listening for 0.0.0.0 on the Azure VM.

Web site host with url in iis

I'm going to host a web site in one of my computers toaccess it from the another computer. (Same local network) This what I have done so far.
Step 1 : Host the web site in IIS.
Step 2 : Using "Edit bindings" I changed the host name.
Step 3 : Then I changed the host file located at "C:\Windows\System32\drivers\etc"
192.168.8.100 mylocalhost.com
Step 4 : Turn off both private and public windows firewalls. (I know this is bad. But for now its fine. I can add inbound rules after resolving this issue)
I try to access to the url http://mylocalhost.com:8082 using hosted environment. It is success, but when I try to access that url from the other computer(in the same local network) it cannot be access. Without the above binding name (mylocalhost.com), I can access to the web site using http://192.168.8.100:8082
I want to access to the website using a url with any computer/mobile device connected to the local network. Can anyone show me a direction to resolve my issue?
Environment Information
Windows 10
IIS (version 10)
Your problem is step 3 - your assumption that the host file on a single client computer will apply to all computers on your network. You need a server of some description for the behaviour you describe.
A hosts file is only used by that single computer to resolve or override dns. Each computer has it's own file and there is no default way of sharing this file with other computers on the network. Your choices are:
Add the host file entry to each device.
Setup a DNS server. your router might support this, and is likely providing the DNS server to your clients via DHCP so no additional config would be nessersary. Just login to its web interface and configure the dns name. If your router cant do it for you you would need a DNS service running on one of your computers and then configure either your routers dhcp/dns to use this new DNS service, or manually configure all clients to use the new DNS for their DNS resolution.
Setup an active directory server and join all your pcs to the domain (setting up AD includes a DNS server).
Some Public DNS providers allow you to specify a private ip in public dns. So assuming you owned the domain example.com you might be able to create an A record my.example.com for your 192.168.8.100 ip address. This would be public, but only devices on your private network would actually be able to connect to your server (ie different physical computers/networks that happen to use the same internal ip).

exposing Azure DNS servers

I have an Azure virtual machine with multiple web sites on it that I would like to expose to the Internet. The VM has Active Directory and DNS installed on it. I created the forward zone (xxx.cloudapp.net) on my server, and added the two web site names to the zone. On the Networks in the Management Portal, I added a DNS server(xxx.cloudapp.net) and gave it the public IP for my server.
So when I try a nslookup from outside of the VM, the names will not resolve. I set the server in nslookup to either the public IP or the name, and it does not resolve. I have logging turned on in the DNS server, but it does not seem to show any requests from my computer.
I must be doing something wrong. Any suggestions? This server is for a demo next week, and worst case, I can buy a couple of domain names.
Try the instance level public-ip address, you will get an ip address per virtual server: https://azure.microsoft.com/documentation/articles/virtual-networks-instance-level-public-ip/

Can a managed website and a virtual machine share the same domain name in Azure?

I have a website hosted on Azure as a managed site. I need to run a separate FTP server and a custom Windows service on virtual machine, but need them to share the same domain name as the site. So what I'd like to be able to do is have mysite.com port 80 go the website, but mysite.com port 21 etc go the virtual machine and connect with the FTP service. How would I go about setting that up?
When a user looks up "mysite.com" they are going to get a single IP address, and there is no way via DNS to return different IP addresses based on the port number you are trying to use. You have a couple options to achieve this solution:
Setup an intermediate routing service that accepts all traffic to mysite.com and then routes the traffic to the appropriate website/VM based on the port number. This is non-trivial and may incur extra costs (you could build the routing service into the existing VM that is serving FTP to reduce the cost).
The easier solution is probably to have a CNAME for www.mysite.com pointing to the website, and a CNAME for ftp.mysite.com pointing to the VM.
