I'm using a WAMP5 server.
I installed Wamp on our school's server and can access the Wamp server in the lab.
But it's not accessible to the dorm.
Why is that?

I've changed it!
But it's useless!

In the lab can be accessed then it should not be allowed all from the problem. Can you ping the server? What is the prompt to open your domain?

There may be hardware devices in between that block access to two of the intranet.

Trouble to ask, you this problem solved no, I am also 2003 server, own WAMP environment, on the server with localhost with this server's public network IP can access, but with other computers, direct access to the public IP, access, but this IP is Ping's pass
