I downloaded and installed the Mac OS X 10.4.8 Combo Update (PPC) for my Macintrash the day it came out.I always look for improvements in SMB performance with OS X updates. My Macintrash is a member of a Windows domain and I have a mobile user profile stored locally. When I’m logged on to the Macintrash with my domain credentials, for some reason, getting a directory listing is very slow when I use SMB to connect to a network share. If I’m logged in as a local user, and connect to a SMB share using my domain credentials, the directory listing is instantaneous.I use AppleScripts to log in to shares. Each script has an alias with a unique icon in my DragThing dock for each share. I just click on the alias in the dock and the share mounts:tell application “Finder” mount volume “smb://domain;username:password@computer/share” end tellI have used Group Logic’s ExtremeZ-IP, and it works great. I used Integrating Macs and Microsoft Active Directory at macwindows.com active directory page for help but there was no mention of this problem.
