login failed for user 'domain\name'

I have tried to setup and installed PHP and MySql in IIS because I want to try PHP web development, and after doing that, I have checked the websites I have created in Visual Studio to check if the websites I have created in ASP.net and MSSQL were affected. When I tried to run the asp.net websites I have created and tried to login to those websites I started to get the error:

Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance"

So what I did was, uninstall MySQL because I was afraid that it was the cause of my problem in MSSQL. After uninstalling, I started to get the error:

login failed for user 'domain\name'

whenever I try to login to my asp.net websites.

Please help me in resolving this issue. Thank you.
