Hi,

I don't know why your Developer would leave without 
leaving documentation of things such as the admin password, 
the source code e.t.c. I believe such thing happen in the real world when 
the Developer is insecure, trying to protect himself, or if the developer 
hasn't 
been treated well by your Organisation (examples of which include owed 
salaries/benefits).

Well I am not helping you if the later is the case but I am going to assume it 
isn't.

Steps to solution

SCENARIO A
1) As Russell mentioned, you will need to look for the code behind of 
btnLogin_Click
method.

2) You will need simulating the problem by adding a break point in that method, 
then stepping through the code whilst attempting to log in using an existing 
username and password.

3) When an exception or error occurs, take note of the message. That will lead 
you to fixing the problem. You can post the error message here if you don't 
know that to do.


SCENARIO B
1) If the source code is not available, and the code behind is not published, 
you will 
need to reverse-engineer the source code using tools such as the now commercial 
.NET Reflector or a free open source alternative such as ILSpy.
NOTE: ILSpy is still in its infancy but is better than nothing.

2) Using the tools above, you can recover the source code of your web 
application from the dlls in the bin folder of the web app.

3) You can then go back and follow the steps in scenario A

Thank you very much.

Below is our Web Portal login.aspx script..
The .net developer quit last year. I am a SAS programmer.
I have no idea what this script does, except it doesn't work.
No error message at login, except "Password or user name incorrect".
DBA sez servers are up and running, and in fact I have run 
simple queries in VS2005  confirming this.
No users can logon, don't know what the admin password is -
left with developer.
 
What steps do I need to perform to troubleshoot?
As in:
Step 1.
Step 2.
Step 3.
etc.
 
Code:
<html xmlns="http://www.w3.org/1999/xhtml"; >

    <title>Login Page</title>
    <link href="css/Login.css" rel="stylesheet" type="text/css" />
