Vista business edition on a high spec machine (dual core AMD, 2GB RAM, 256
graphics) zips along quite nicely in it's own C:\ drive, browsing internet,
local resources etc, but browsing to any shared network drive takes about 2
minutes just to list the contents of the folder, and installing a piece of
software takes forever.
Details:
Windows updates applied, Firewall off, DHCP all OK, Win2003 servers, anti
virus not installed, fresh install, logged in as domain admin.

Any ideas? Same machine formatted as XP is fine.
