MS 2003 web server problems, basic authentication, anonymous access

we are running 2003 frontpage for production, and 2007 Expressions web for developement, When, we save a uploaded file (web image) or a web page link in frontpage for productions to our web server it just hangs there for 5 to 10 minutes before working or timing out. It works slowly 95% of the time. Does anyone know of any type of problem it would have with these two applications working together? Or, any other suggestions about the problem?
