I am not sure what could be causing this issue other than maybe some user error on his end because I am not in front of his machine.  However I did read about issues with a firewall and logging in.

I removed the remember me option since it was causing problems (Possibly a persistant cookie setting issue?) since then I have had no issues with having to repeat logging in.

I am however having a problem with a person trying to log in behind a hardened firewall.  I am thinking maybe has to do with the database security settings possibly.

I setup a new appPool just for this one DNN app instance with its own user and password that matches the username and password in the database.  I am using sql express on the local machine server.

I can use the user password connection string however the integrated security string I have not had any success.  I was thinking this may be a safer way to connect to this database and keep the plain text off the machine.

I must be missing a step to do this properly however.  Is it that much more secure to have it connect with integrated security rather than the SQL username/password way... and if so then what step am I skipping?  or possibly what connection string am I suppose to be using in the web.config file.

Thank you.
