Mac opening times unacceptable.
We have a windows 2008 R2 AD server for file and print running in a school with PCs/laptops plus 50 or so macs (Snow Leopard) connected to it. AD binding and AD authentication works fine for all machines (after maxing out the DNS wait time thingy in one of the plist files for SL). The problem we have is that when we try and open relatively small documents (1 Mb or thereabouts) from the macs, it can take up to a minute to open when connecting over our managed wireless network. Deeply unacceptable. I shudder to think what sort of performance we'd get for anything larger. It seems marginally faster if we connect via cifs, but nothing to write home about. Windows machines work fine over the wireless. Any ideas?
