Using the Home edition of Avast 4.7.942 on my laptop running Vista
Enterprise and my laptop is connected to my SBS 2003 network (for home use

) that has ISA 2004 installed.
I also have another desktop running Avast 4.7.942 with XP Pro SP2 connecting
through the same SBS and ISA server.
The XP Install updates just fine. The Vista install will not update at all.
Both have the SBS firewall client installed and both Avast installs are
using the same Proxy settings (using IE settings).
From what I can see the Vista install appears to be making it as far as ISA
and being denied because of authentication reasons. Also, When I go into the
program settings and try to run a test connection the dialog box will not
show up on the regular desktop, it insists on showing up on the alternate
desktop through the Interactive Services screen.
As I said I have the feeling that Avast is running under a non-admin context
and thus its attempts to talk through the firewall are being denied.
Anyone here have any ideas?
