Nothing is wrong! I assume somebody else did the setup at work.
By default wamp comes with a secure configuration so beginners dont get hacked.
On
'Box A' the box with Wamp installed you will need to either:
1. 'Put Online' using the wampmanager icon menu.
This will change the security for your developed sites to allow access from anywhere.
Then do 2. as well
OR
A better solution would be to edit the httpd.conf ( using the wamp manager icon menus )
Look for this section
<Directory "d:/wamp/www/">
...
...
# onlineoffline tag - don't remove
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</Directory>
and change it to
<Directory "d:/wamp/www/">
...
...
# onlineoffline tag - don't remove
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from 192.168.0
</Directory>
Add the extra line so that the online/Offline processing does not get compromised.
This would allow access only from any PC on your internal network and of course 127.0.0.1 the localhost.
2.
If you want to be able to use phpMyAdmin/sqlGrind/sqlBuddy you will also have to make that change to these 3 files as well.
c:\wamp\alias\phpmyadmin.conf
c:\wamp\alias\sqlbuddy.conf
c:\wamp\alias\webgrind.conf
