Installing Postgres 8.1 on Windows Server 2003 R2

Has anyone tried to install Postgres on Windows Sever 2003
version R2? R2 is actually shipping as a 'new' Microsoft
product- it's basically an interim update to Windows Server (
http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.msp
x <http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.mspx&gt; ).

Not that I know of, but it's been on my list of things to try :-)

I've installed Postgres on other versions of Windows with no
problem, so I'm afraid that the error I'm seeing now is
related to some great new 'feature' from Microsoft. Here's
the error message returned by Postgres before install begins-
Error binding the test network socket: 10013

That error means: An attempt was made to access a socket in a way
forbidden by its access permissions.

Microsoft Antispyware has been turned off (closed the
application) and Windows Firewall isn't running. There's no
other AV or firewall software on this system yet.

Any ideas on what might be going on?

It certainly *sounds* a lot like a firewall issue :-) I'd double and
triple check that. We've seen it several times before and it has AFAIK
always been a firewall.

That's what I was afraid of... it's a new install of Win Server 2003 R2, so
I can rule out any third party firewall. Windows Firewall is NOT installed.
And I've installed Postgres on a Windows XP box behind the same router, so
it's not a router-firewall issue.

It's probably a new R2 feature, I'll ping someone at Microsoft because
I don't have a clue at this point what the problem is...
