Filemaker Pro 7 Server Advanced

Windows 2003 Server.

MAC clients

The fp7 database can be shared on the LAN but cannot log in from IE 6.0 with
a defined Account and password.

Can anyone provide help on solving this problem?

This is what I know for sure:

1. IWP is toggled on
2. The Advanced Options has the Privilege Sets enabled for the defined
accounts
3. The Filemaker Inc updaters to v3 have been installed.

Is it Windows 2003 that is causing the problem?
Is it a router config problem?

If you any possible reason(s) then I would appreciate clear instructions on
what has to be done to get this database accessible from the Internet.
