How to access the site created in the server from other systems.

If we want to access the Sharepoint site created in the server from other systems we have to check for the following things:
1)Whether the User is having permissions are not.
This can be checked by looking into user permissions and groups of the site.
2)Check the firewall settings this can be done in the following way:

start->Controlpanel->Windowsfirewall->Select the tab Exceptions and click on addport give the servername and portnumber of the site you want to access.
Cheers now u can access ur site from any other machine in the lan.

3)if you want to access all the sites then you just turn off the firewall settings(Not recommended).
