Hi Everyone,
I have this problem. I am done with the coding, and I want to access it using a url. The program is working perfectly in my local computer, but when I try to go to IIS, add a new website, assign port, like what I did in my past programs. The problem is when I try to go to the url, it is giving me the error:

Login failed for user 'test1\Test2$'.

Here are some useful info:
Test1 is the network,
Test2 is the server and the IIS that I have located the development file

I developed the system using my computer but IIS is in the server

Is this an sql server security issue?

I searched the internet already and havent found the solution to my problem, I hope someone can help me out on this.

Thank you very much in advance.
