I was tryig to configure certfication server on a sharepoint server ,after installing it,I tried to open the sharepoint site,but message displayed ,the page cant be found,tried to open central administration,couldnt open it also,so opened IIS and found that the sharepoint site had disappeared.Is there any way for me to restore back the site

Are you able to Application pool and web Sites option in IIS? Try to connect your IIS with server and tell me the exact problemCheers, Hemendra-MCTS

I ran the sharepoint configuration wizard and chose to overwrite to a new site,then restored from a backup and site is restored but the reporting was configured within the sharepoint ,now whenever I opened a report ,this error is displayed"An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. " And when I opened the IIS,no sign of report server
