hi I have sharepoint installed on server farm earlier but due to some error I was not unable to start sharepoint web application service.Repairing the officeserver and running the config wizard didnot solve the error.So I remove the office server from the application server and reinstalled it Now when I run config wizard with existing database it throws error system.IO.Directory Notfoundexception while provisioning the central admin further update on this when I try to do new sharepoint instalaltion then also I get some error.This error comes after step 7 showing that site is provisoning and then it immediately throws error system.io.directory not found Any help will be greatly appreciated

Hi, Could you please check the event viewer and ULS logs to find the error messages there? Lu Zou
