Looking at the event log, I'm getting this when I try to access the central admin page:
The description for Event ID 8214 from source Windows SharePoint Services 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
A request was made for a URL, http://localhost:2222, which has not been configured in Alternate Access Mappings. Some links may point to the Alternate Access URL for the default zone, http://servername:2222. Review the Alternate Access mappings for this Web application at http://servername:2222/_admin/AlternateUrlCollections.aspx and consider adding http://localhost:2222 as a Public Alternate Access URL if it will be used frequently.
