Correct ASP scripting for website admin area

I have a client who has a Flash website that draws content from a Microsoft Access database as they are hosted with a rubbishy hosting company who are Windows based and have poor support and no SQL database plans, however, the client does not want to move. We had the website setup and had an ASP admin area that connected to the database and allowed the client's staff to update the database and the website content. The site was hosted on a Windows Server 2003 platform. However, the host company have just moved the site over to a new Windows Server 2008 platform and now nothing connects to the database on the frontend or the admin area. I think it's just something to do with the ASP scripting connecting to the database. I need someone to solve this issue and correct this all within a few hours.
