can’t access apache web server

I installed apache1.3.22 on a RH7.1 with the following config options:

SSL_BASE=../openssl-0.9.x \
./configure \
–enable-module=ssl \
–active-module=src/modules/php4/libphp4.a \
–enable-module=php4 \
–prefix=/usr/local/apache \
–enable-shared=ssl

I can browse the pages on the machine where apache is installed but I can’t connect to
this web server from other machines on the network ( both MS Windows & Linux machines).

I’ve edited the httpd.conf file, do I need to configureanything on the other machines on the network?
