I am running an application in WEC 7 and trying to connect to remote system, and I am using QFtp for transferring some data. When I try to connect to remote host using connecttohost, I am able to find the host but the connection is not successful and shows me error connectionrefused from remote host.
I tried the following things :
I made an exception in firewall for ftp connections so that remote host can accept the connections.
I turned on the discovery for the folders.
I added an inbound rule for port 21
I checked the option for ftp in control panel/Programs/program and features/turn on windows features/internet information services ,
FTP server.

I have a local MAC machine that RDPs into a windows VM. On that windows VM/desktop I have Power BI Desktop installed along with the Cdata PowerBI/Quickbooks ODBC driver (https://www.cdata.com/drivers/quickbooks/download/powerbi/).
On a separate server (which I can RDP into from the virtual machine) I have quickbooks desktop installed (https://www.acecloudhosting.com/) and in single-user mode (opened a company file w/ an admin user). On that server I have also setup QuickBooks Remote Connector (http://remoteconnector.com/), which essentially is used to create an authenticated connection to QuickBooks. This "remote connector" also acts as a lightweight web server that listens for incoming requests (such as a power bi direct query) and uses that to communicate with Quickbooks hosted on a separate server.
However, I keep getting an HTTP protocol error and not sure if it is because the ports are not setup properly or if something in my ODBC connection is incorrect. It is very odd that I can RDP into the remote server from my VM, but when I try to ping the server my request time out despite allowing ICMP responses in the windows file sharing options so I find that odd.
I have worked on this for about 4 hours, but have run out of things to try.

I have developed a asp.net website and published in a server.Whereas everything works perfectly in that server if i give browser from that IIS manager, and in server ( published system ) everything works perfect.But i need to access the same published application also in the other systems also ( which are connected in same network ). How is it possible..??
NOTE:
1. Used IIS 7.
When tried to connect from another system from same networ getting error as follows
The socket connection to 172.31.7.243 failed.
ErrorCode: 10060.A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 172.31.7.243:90
If Your are accessing Your application on Hosted Server like this then just replace
localhost with ipaddress of hosted server to access it over the network
[localhost]/MyProjectName
then like this:
[IPaddress_of_HostedServer]/MyProjectName
It is possible that the HTTP traffic on port 80 incoming from the local network is blocked.
You should check if ISA server is installed on your server and if so if HTTP traffic on port 80 is allowed or not. If it's blocked try to allow it for the local network ip range.
Edit: Or port 90 as your error code states, but why are you working on port 90?
Why I am not able to connect to remote server from asp.net website whereas it is connecting from SSMS
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I tried all the possible solution suggested in this link
I checked Followings as given in the above article, they are enabled/running
SQL Server is up and running.
TCP/IP enabled in SSCM
Opened port in Windows Firewall
Remote Connection enabled
SQL Server Browser Service running
I searched for sqlbrowser.exe but it is not found in the given directory.
Finally I switched off Windows Firewall but still it is not working.
UPDATE: we are connecting to sql server using a custom user created on sql server (not sa )
I have user account credential to Remote connect to server.
I tried to change LogOn to my credentials (administrator) . in Windows Services SQL Server (MSSQlServer) and SQL Server Agent (MSSQL Server) services.
Double check your connection string - are you connecting to a hostname that needs to be added to your Hosts file? For example "dev-sql1" but without a matching entry in dns or hosts file.
If you have created a custom user, can you check if logins are disabled for the user?
In SSMS, goto Security, right click user, Properties -> Status, Login - Enabled.
Hope this should fix it.
Three possibilities and they are not mutually exclusive.
Most hosting providers disable remote connections to SQL servers. Check with RackSpace if blocking port 1433
The SQL Server needs to be reconfigured to accept remote connections. See http://support.microsoft.com/kb/914277
You have to use a different connection string. See http://www.connectionstrings.com/sql-server and look for Connect via an IP address
I got the same issue but with mysql server. Rack space had two mysql server address. One for connecting from outside their local network and one for connecting from inside the network. you will have to use the address that is required to connect from inside the network.
I was wondering if there is a way to see if a server blocks outgoing connections. I am trying to connect to an external database from a client's server.
This is the error I get:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
Edit:
I forgot to say I only have access to the plesk control panel. That's why I was asking if there is a way with asp.net.
When you say "server", do you mean the asp.net server, or the SQL server? And are both machines on the same network? Is this hosted?
Sql Server:
They can remove the OPENROWSET functionality, so you can't connect to remote servers, regardless
I doubt they are giving you access to linked servers in a hosted env
ASP.Net
You can try to connect to the other server via a regular connection, and see if that works.
Download a tracert component, and use that to try to trace from your server to the remote one.
If it dies somewhere inside your network, then that is your answer (it is blocked)
If it works, the outbound is open. Doesn't mean 1433 is open though.
If it dies after, not blocked, but maybe the remote is blocking icmp echo
Remember to try to tracert to somewhere else that you know works
It will be hard to tell what is killing the connection on 1433, if you can get to the server using other means. Could be the firewall, their fw, etc.
The trusty telnet method:
telnet theserver 1433
If this times out, the server is not listening. If the screen blanks and you can type something, the server is listening and no firewall is blocking the connection.
In Vista and Windows 7, you have to install telnet as a Windows component from Control Panel -> Programs and Features.
I have a login page that works in my local development environment. When I push the site onto the web server, i am getting this error when trying to login from the asp.net login control.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I cannot figure out why it does not work on the server. Do I need to add anything or change something in the web.config?
This support article may help. It may also be a firewall issue or an authentication issue on the new setup (but the error message makes that less likely).
For resolving error 26 in sql server you need to do the following steps.
At Server System
1. Under surface area configuration manager-Open up remote connections.
2. Add into firewall 1433 and 1434 port no as n exception.
3. Open port 1433 on router for WAN access.
4. Add client machine ip address as an exception to your antivirus or allow LAN settings in antivirus.
5. Now try to check if both client and server are connected to each other.
for this type "ping IP address of remote system" at run and if reply is obtained then do same for server machine.
If reply is obtained from both machines.
Open Sql server and try to connect to remote machine which allow remote connections using its ip address. U will surely get connected to server machine
See this video
Check to make sure TCP/IP is enabled on the SQL Server. For whatever reason, named pipes and TCP/IP is off by default. Also make sure you are trying to connect to the correct instance (maybe you are using ./SQLEXPRESS locally and on the server SQL is installed on the default instance). Lastly, make sure the database you are trying to connect to exists on the server.
