MS Access database issue

Yesterday I installed Win XP and MS office 2007 and then tried to browse a site at my local server (i.e localhost/pixelmanagers/default.asp) but for some unknonw reason I am getting following database connection error.

(Unspecified error
The connection cannot be used to perform this operation. It is either closed or invalid in this context.)

I am using MS Access database and the path to database is correct and there is no problem with the db path defined in connection string.

you have to give the read and write permission to the database folder for the IUSR account…
