Hi ,
I am new to this forum,
If anyone knows how to create ones own webpage and host it in the intranet of the company (in which he/she is working) pls let me know abt it.

You would need to talk to the sysetm administrator of your company to find out if they are running an httpd like the apache server.
If they are running one then ask how you can post your html pages for them to be available to the others on you system.
What OS is it?
