After updating ASP.NET version from 1.0 to 2.0 , i am getting an error
like this after trying to open the sharepoint Central Admin page.
Unable to connect to the configuration database. Ensure that the
database server is online and that the configuration database exists.
If the configuration database administration account password recently
changed or expired, see the Microsoft Office SharePoint Portal Server
2003 Administrator's Guide for instructions on how to update the
password. If the configuration database or database server is
permanently unavailable, click Disconnect from configuration database.
