>>Do you have frontpage server extensions - ie, the ability to run asp?

Thanks for the reply, Wayne..

It has, now I can browse, but the Outlook Web Access has still problem, I received the error below..

HTTP 500.100 - Internal Server Error - ASP error
Internet Information Services

--------------------------------------------------------------------------------

Technical Information (for support personnel)

Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: 'Application(...)'
/exchange/usa/LogonFrm.asp, line 60

This error according to exchange documentation can be fixed by reinstalling the Outlook Web Access, but to no avail..

Any tips on this?

Thanks..
