Kaisy hai aap sab?
Dosto mere Machine par PHP, MySQL as Database, and IIS
as Web server installed hai...
Ab problem ye hai k jab mai MySQL configure karna chahta hoon tu last configuring option mai zeel ka error deta hai:

[H1]
Error Nr: 1045
Access denied for user 'root'@'localhost' (using Password: NO)

If a personal Firewall is running on your machine, then make sure you have opened the TCP port for 3306....
[/H1]
(Sometime give YES instead of NO)
