NT Logon & WebCheck

Hello experts,

I have just finished intalled web Intranet and I will implement it in my Windows NT domain. I want every user has Internet Explorer starts up with their every Windows NT logon locating my server's intranet URL automatically, so that I don't need to go to each workstation and put URL in their IE.

Would anybody please help me how? Or what is the software which has this functionality?

Any help would be greatly appreciated.

Thank you,
David
