Just thought I'd post this to share and see if anyone else in a similar situation is seeing what I'm seeing.. I have a bunch of Tiger boxes bound to Active Directory. All the users have cached (mobile) logins and use the autosync feature to sync their home directories to a mounted SMB file share. This has been working great for months. Until 10.4.3. I think a bug was introduced in 10.4.3 and it's "includes fixes for: - AFP, SMB/CIFS, NFS and FTP network file services". For some strange reason now, 2 of my user are starting to have random kernel panics associated with SMB.

No crazy data has been created to be sync'd. There's not much in the way of time stamping that points to anything. The only commonality between the 2 is, 1) they both have Macs (though one is a laptop, the other a quicksilver), and 2) both user are Chinese (which is a non-issue, but is a commonality). We all joked that it's the first Mac virus, releasedreleased by Microsoft, transmittable via Mandarin. So what have I tried to fix it/work around it? Repaired Permissions (nothing unusual in the results). So far on one, I've turned off AutoSync and made it a Manual sync. I want to see if it's the autosync that might be breaking. For the other, I'm just trying to reinstall the 10.4.3 Combo Updater, but I cannot seem to download it from Apple. Every time I do, the checksum verification fails (tried on multiple Macs). So there's something f-ed at Apple right now. But anyway.. I'll post back with more results and troubleshooting later on. Anyone else seeing this?
