I am getting the following error while asp.net app trying to connect database.
Login failed for user 'IIS APPPOOL\myAppPoolName'.
I use ms SqlServer 2008 r2, windows server 2008 r2.
This happened when I've just moved the application and database from one server to another.
I thought adding a new user to database named 'IIS APPPOOL\myAppPoolName' but when i try it, I'm getting following error on adding new db user wizard:
'IIS APPPOOL\myAppPoolName' is not a valid name because it contains invalid characters. (Microsoft SQL Server, Error: 15006)
How can I fix this?
Thanks in advance.
