I installed locally commerce server 2002 sp3 on Windows 2002 in a domain. When I try to connect to BizDesk as local or domain administrator, I got the following error:
"An error occurred while accessing the Business Desk. Contact your system administrator."
It seems that in IIS 6.0 Active Server Pages (ASP) was prohibited. Just go into "Internet Information Server Manager" and look under "Web server extensions". Change the "Active Server Pages" to Allowed.
