Have you tried to disable the RSS/TCP Chimney feature on the 2008 machine?

Then I would try to detune SMB signing on the domain controllers. It's
not recommended due to security, but this may be what's going on. It
was a default change we used to make years ago when 2003 came out.

Please read the following for more info:

Slow performance via Leopard Connection - SMB Connections...
Connecting to the 2000 File server via SMB from OSX Leopard is very
quick, drive mappings work, file copy to and from is ... OSX Leopard to
Windows 2000 Server - 16.8s - Wow! ... Mac's on the other hand are very
slow. ...

Other than disabling SMB signing, I'm sorry, I am fresh out of ideas. I
would suggest to place a call with Microsoft PSS, if this is causing a huge
problem.. I assume you've tried the Apache forums or support?
