Hi Suruchi,
Perform following checks
1) Check using the url
http://<HOSTNAME>:<Port>/ContentServer/ContentServer.dll?serverInfo
Whether content server is running. If not start it using
My computer Right click -> Manage -> IIS -> Web applications -> SAP Content server
Right click and start.
2) Check whether MaxDB database is running . You may use dbmgui or database studio to connect to the MAxdb database.
Hope this helps.
