I cannot start the Apache service on Windows.
Have you checked that another program is not already using port 80? If you start a command prompt and type:
netstat -abn
You should get an output similar to:
C:\>netstat -abnp tcp Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:80 0.0.0.0:0 LISTENING [httpd.exe] TCP 0.0.0.0:135 0.0.0.0:0 LISTENING RpcSs [svchost.exe] TCP 0.0.0.0:443 0.0.0.0:0 LISTENING [httpd.exe] TCP 0.0.0.0:445 0.0.0.0:0 LISTENING Can not obtain ownership information TCP 0.0.0.0:554 0.0.0.0:0 LISTENING [wmpnetwk.exe] TCP 0.0.0.0:1025 0.0.0.0:0 LISTENING [wininit.exe] TCP 0.0.0.0:1026 0.0.0.0:0 LISTENING eventlog [svchost.exe] TCP 0.0.0.0:1027 0.0.0.0:0 LISTENING Schedule [svchost.exe] TCP 0.0.0.0:1028 0.0.0.0:0 LISTENING [lsass.exe] TCP 0.0.0.0:1029 0.0.0.0:0 LISTENING [services.exe] TCP 0.0.0.0:1030 0.0.0.0:0 LISTENING PolicyAgent [svchost.exe] TCP 0.0.0.0:2869 0.0.0.0:0 LISTENING Can not obtain ownership information TCP 0.0.0.0:3306 0.0.0.0:0 LISTENING [mysqld.exe] TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING CryptSvc [svchost.exe] TCP 0.0.0.0:5357 0.0.0.0:0 LISTENING Can not obtain ownership information TCP 0.0.0.0:8042 0.0.0.0:0 LISTENING [opmantek_server.exe] TCP 0.0.0.0:10243 0.0.0.0:0 LISTENING Can not obtain ownership information TCP 192.168.0.86:139 0.0.0.0:0 LISTENING Can not obtain ownership information TCP 192.168.0.86:2869 192.168.0.1:3115 TIME_WAIT
Look for a program using port 80. In this case, not the output
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING [httpd.exe]
That indicates port 80 is being used by the executable httpd.exe (in this case, apache). You should no see any entries using :80.
If there is another program using port 80 either stop and remove it, change it's port (if possible) or install Open-AudIT on another machine.
