This is caused because there is a database running on your computer  In my case  it was an Oracle data base  By default  everytime you start your computer  the services of the database automatically starts    Go to Start    find Oracle or whatever data-base in the list of programms    and manually stop the database  It appears that there is a conflict of port

even i faced the same problem  The possibility of this could be usage of same port by two or more application process  In Some cases you can use different port number which will avoid this problem  but in other case you have to manually kill the process with help of command prompt   The command to kill is  In your command prompt first enter this command  C  Users A611003 tasklist  After this you can able to see list of process running with process ID   For example    From this select the process you want to stop  for example consider the process id 304 is your server and you have problem with that  Then enter this command   C  Users A611003 gt Taskkill  PID 304  F   This will kill that process now you can clean  publish your server and start it   Note  If you fail to add  F in the above command it does nothing  It is the force kill  you can also try   for list of available options

I ll assume that uninstall and reinstall Tomcat is not acceptable to you  The screen shot show basic auth challenge screen from browser and on the default app  So most likely you have set up users on the tomcat using the      conf tomcat-users xml  Try going through this guide https   tomcat apache org tomcat-7 0-doc realm-howto html UserDatabaseRealm  There are several other realms that you could have possibly used  Hopefully you will remember when you start reading the doc

Some other application like oracle  is using the same port number  So you should change the tomcat port number in apachetomcat conf server xml  Privious---     lt Connector port  8080  protocol  HTTP 1 1                 connectionTimeout  20000                 redirectPort  8443    gt    Updated ----    lt Connector port  8088  protocol  HTTP 1 1                 connectionTimeout  20000                 redirectPort  8443    gt
