I'm wondering how can I possibly troubleshoot this. One of our client is having trouble connecting to our server, I went in and used HeidiSQL to see if it can simply establish a connection. It seems that it can connect to the IP address but not the address. All of our clients connect fine except this one client.
What could be the issue? Could it be the host files?
Connection is made through connection string
Have you tried to resolve that name to IP? Might be a DNS issue. In the end an easy fix will be to edit the hostfile to resolve the name to your IP, but this requires maintenance on the machine if that IP ever changes.
A better fix will be to figure out why the name isn't resolving to the correct IP address.

I am running into an issue where I need to provide FQDN anytime I am entering server names in and it really is bothersome. When I log into SSMS using just the host name, I get a "network-related or instance-specific error". However, when I use the FQDN, it works. What do I need to do to be able to just use hostnames on my machine?
I also work on Power BI reports which points to servers that are not FQDN. So when i make edits and publish, it crashes the gateway due to server name inconsistencies.
Please let me know any quick troubleshooting tips or if you need additional information, i'd be more than happy to provide.
It seems that hostname of your server cannot be resolved. In this case, you can create hostname mapping for your SQL server (which will only work when you are connecting to your SQL server from your computer)
Open %WINDIR%\Windows\System32\drivers\etc\hosts file with notepad
at the end of file add your hostname and ip address with the below format
save and close. Now you are able to connect with the given hostname
example
192.168.1.250 sqlserver.local
I was able to connect to my rds through chrome,IE,Firefox. Sometimes the connection would be refused. Now it is just refusing all connections, I'll be able to supply any information needed.
Found the issue, I took it off of DHCP for a test and it got a duplicate IP when I re-assigned it . All is good now !
In my java program, I connect to a mysql database on my server, but I have to go into my cpanel and add my ip address to be able to remotely access it.
Is there a way to allow all connections or add a mac address instead?
Thanks to Rugal, I got it to work.
I used %.%.%.% as the access host to allow any connections and it worked.
From my understanding of a DNS Server, a simple explanation is that for a given hostname the DNS server uses a lookup table to return the IP Address of the hostname.
For one of my projects, I used to connect my client to the server through a wifi network, and specify the IP Address and port at which the server is listening on the client.
A new requirement has come which asks to specify a DNS server in the network settings, and the DNS server in turn returns the IP Address and port number of my server.
I went through online to check the request/ response to A DNS server, and I found many places it is mentioned that port number is not sent by the DNS Server. Is it right?
I have coded my project in Visual studio 2005. Is there any libray/code of a DNS Server which I can integrate with my existing visual studio project? And is it possible, that for a particular host name I can specify the port number in the response?
I have checked many source codes for DNS Server in C like ldns/ bind , but I have not found a way to integrate with visual studio.
You can specify an additional information about given domain in TXT DNS record. So, you could add text tag:value part into your domain TXT record.
Might this be what user is trying to define? DNS SRV record
That just doesn't make sense, the port is not part of the host's domain name. A given host (=a single domain name) can run any number of applications, i.e. have any number of ports open.
Your idea would require that some form of identity of the desired application was sent to the DNS server for the the look-up, or that it could reply with a list of running services and their ports. It just doesn't work like that, at least as far as I know.
There's nothing stopping you from running a web server (normally on port 80) on any other port, such as 8080 as is often done during development. The URL will then be http://example.com:8080, and since the browser only looks up the example.com part in DNS there's no way for the DNS to override the port number.
I don't know of the default server name. Can you please help me because I need to work on our project to connect vb.net with wamp server, and for that to happen, I must know the server name that I will put on the codes. Please, thanks in advance.
The WAMP server doesn't maintain a name. You connect to it via an IP address... do you not know the IP of the machine it's installed on?
If it's on your own computer, you can connect to the Sql server from code by connecting to 127.0.0.1:3306 (default port).
If it's not on your machine, find the ip address of the machine it's running on by going to the command prompt and typing 'ipconfig'.
Then use that IP address and port 3306 (or whatever port you defined, 3306 is just default)
Default access will be via localhost or 127.0.0.1. Might not work (rarely) if it was modified before.
The following should work provided (provided mySQL port is default at 3306) :
Dim connectionString As String = "Driver={MySQL};SERVER=localhost;DATABASE=student;

Just check connectionstrings.com, one of the best resources out there.
