You might not like this answer, but I found out by Microsoft, the slowness is
due to the NTLM setting on IIS.  You need to change it to Basic
Authentication.  You must change this setting within the System Manager of
Exchange 2000, to perform this, do not use IIS to switch authentication.  OWA
was design to use Basic Clear Text Authentication with SSL.  You should see a
huge performance increase.

Subject: [isalist] ISA & OWA

Hello all,
I had to rebuild my ISA Server over the weekend.
I have everything working that I did before the rebuild, but I find now the
Outlook Web Access is very slow coming up when I am accessing it externally.
Internally it comes up pretty quick, which is expected.  I am using a DSL
line externally.
Does anyone have an idea to remedy this?
