You are trying to use integrated security in your app (as is shown in the
line numbered code where the connection string is shown). This looks like
it's running on 2003 server, because asp.net runs under 'network service' by
default in this case. The 'network service' account doesn't have access to
sql server, hence integrated security fails.
The page source code you show is using a username/password to connect, but
clearly your client modifed the connection string to use integrated
security.
Don't write your code as asp.net script, since then your clients will start
modifying it in unpredictable ways, and you will have a support nightmare on
your hands. You should give them specific instructions on setting up a
username/password on their sql server and have them put this in web.config
or someplace like that, and have your app look there for connection
information. I also noticed you are using the old ASP method of writing out
all the HTML on your page - this is pretty antiquated. I would recommend you
take advantage of all the asp.net server controls now available to do this
sort of thing.
