I have created a windows application and the sql server is hosted in a server and I connect using webconfig.
Have created installer for it, works fine for me.
But when someone else outside the network tries it will get an error with sql connection.
any ideas?
Thanks
Your question as it is now is way to vague to give a proper answer. Here’s an msdn link with information about troubleshooting sql server connectivity issues:
