Windows 2000 and IIS version 5

I am trying to setup an Intranet site. I have communications betwen the workstations and the IIS server. However, I the web-site I created continues to send back an error. The error I get when connecting to the Intranet site is:
Technical Information (for support personnel)
Error Type:
(0x8009000F)
Object already exists.
/localstart.asp, line 18

Browser Type:
Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Page:
GET /localstart.asp

Time:

Any ideas? I am very new to IIS….
Thanks,
Scott
