Iis, Apache, Port 80, Csrss.exe

hi

in windows server i disabled iis and run apache without any problem

but port 80 is used by a process named csrss.exe and i can not stop it at all

how can i fix this?

thanks

change port to 81 in apache/conf/httpd file and access your application by localhost:81/appname

thanks but i only want to use port 80
