Here's some more guesswork. Does it seem possible that msiexec is
trying to verify the revocation status of the certificate used to sign
the python .msi file? Per
it looks like crl.microsoft.com is the host; this is hosted on akamai:
crl.microsoft.com is an alias for crl.www.ms.akadns.net.
crl.www.ms.akadns.net is an alias for a1363.g.akamai.net.
There are various things you could try to verify this. You could test
with simpler .msi files where one is signed and another is not signed
(I'll leave it up to you to find such things, but ORCA is a common
"test" .msi file). Or you could take a verbose log of the installation
process (msiexec /l*v python.log python.msi OR
http://support.microsoft.com/kb/223300), sit on the prompt for network
access so you can uniquely identify the log's timestamps, and try to
identify at what point of the installation the network access occurs.
Once that is known, more steps can be taken to identify and resolve
any actual issues.
