I notice I'm late to this thread, but I'm awake and so might as well add my imho.
Our office has two PowerBooks (both on 10.2), 2 XP Pro boxes, 3 Win2k laptops, and a couple older NT boxes (one as our EDOX print server, another as a SCSI scanner box).
Our main fileserver is a Pentium Pro 200 box running Novell 4.11 on several ultra wide SCSI disks. Of course OS X can't deal with the older Novell servers so we have added two scratch-built SME servers. All the Art Dept files get stored there as well as personal employee websites and website beta-testing.
One of the Macs is mine and it shares a desk with my XP pro Workstation. (I'm not a switcher just yet but I'm completely infatuated with the BSD underpinnings of OS X and with the two SME servers.)
For some reason the Macs periodically lose their connection with the two SME servers. An error message pops up that the server is going down for maintenace (spelling?) and the share is dropped. This causes problems with linked files in Quark and InDesign docs and general headaches for the 'creative people." Seems that when we connect through SAMBA, connections don't drop, but it takes longer to mount.
I've been working on it for a while now, and I'm not sure if it's the way the Macs are setup, or an issue with the appletalk conf on the server.
ANother thing that's a pain is that the Macs create a new directory within every directory called 'AppleDouble.' It's hidden from the Macs but Windows users who are showing hidden files can see it. Not sure if it actually takes disk space away, but it's a little annoying to burn a CD based on a whole file structure only to have the client call me and ask what the AppleDouble dirs are for.
