Asp .net: C#
Visual Studio 2008, and 2013
I have a webApp that allows individuals to register for educational training. webUsers can click on links to view pdf and if the want to register for a training course, hey fill out: 1) a training form; 2) click the submit button when finished; 3) after clicking the submit button, their information is submitted into the DB; 4) an confirmation email is sent to the user and webApp Registrar.
After the information is submitted into the DB, no emails are generated. It use to take about 1 - 3 seconds to display the confirmation page, now it takes about 30 - 60 seconds is that. It seems like it hangs when it is executing the send email logic. The problems seems like the app but I am not sure.
Did anything change
Yes, the IT department moved the server to a different network: The old IP is 192.168.16.56 and the new ip is 10.10.36.11. users can send and receive emails from the mailserver to my outlook client on the server without issues. I checked the firewall and no issues. It seems like the problem is limited to the webApp. I checked DNS and IIS and the IT guys changed all the old IPS to the new IPs. I am thinking there has to be another setting, maybee in IIS, visual studio to cause the web app to not send an email. Please Help!!!
