Subsequent DB access permissions fail?

I have a website built from the CodeSmith/PLINQO sample generator - it works like a champ on the development PC; the app will do exactly what I need very nearly straight out-of-the-box; but...

When I deploy it, only the first page works! The main page returns the list of tables just fine. Any drilldown to open the menu specified tables does not. The failure message is "Login failed for user 'NOVATECHESG\Appserver$'. NOVATECHESG is our domain name and the application server is "Appserver"; I get that. But why the change? I have experimented with the permissions on the host server, but nothing I do there seems to matter...

I have anonymous user turned off on the website; so I login when accessing the webpage - Windows authentication is active at both the web and DB servers.

Why does the first call work and subsequent calls don't? Why would they not use the same username\password?  Is there a setting in the project that I'm missing?

Any constructive advice would be appreciated!

Thanks
