Is the apache modul mod_rewrite loaded on that server?
Go to admin/system/server info and under configuration, apache2handler in line Loaded Modules is should be displayed.

my server API is : CGI/FastCGI
and in my server info its not showing what u told.
what should i do now?

Any log message?

No logs

If that is the case, please contact your service provider to get more info.
I hope this works fine:
viewtopic.php?f=22&t=689
so that problem is with the httpd.conf.

Okay I will do it and let you know:)
I want to know what kind of problems arises if we use
The cart switching off the URL aliases?

In the .htaccess file change
RewriteRule ^(.*) index.php/$1 [L,QSA]
to
RewriteRule ^(.*) index.php?$1 [L,QSA]

i am using windows package of hosting so, can you please tell me what should i make an request to our hosting service providers so that it works fine?

They have to enable mod rewrite in apache http config file for it to function.
Either that, or move to a Linux/Unix server if they have that option. It would be more secure.
