We have a OS X 10.4.4 Server on a 1ghz G4 with 1gb memory that's only doing file serving (AFP and SMB). 8 Mac clients (10.4.4) log on with network home folders. About 25 other people log in infrequently via SMB.

I'm having a problem with some of the Mac clients reporting very slow file launches and saves, but it's intermittent and doesn't affect everyone. I've managed to "fix" the problem (by not really doing anything) but it comes back usually within a few days to a week or two.

All applications are installed on the local hd's. Only the home folders are on the network.

Here's an example of the troubleshooting I've done. Assume client A has problems but client X doesn't and client X has *never* experienced this problem.
Log in as client X on a particular Mac. Launch various files and save various files in Illustrator. No problems.

Log in as client A on the same Mac. Launch the exact same files and replicate the exact same saves. Client gets the spinning beach ball for several minutes before the file finally finishes launching/saving.

For client A, I've tried:
    Temporarily moving the preferences folder. No effect.
    Repair permissions. No effect.
    Manually change ALL files/folders in home folder to *everyone* with RWX permissions. No effect.
    Manually move out the fonts folder (When Illustrator launches, it seems to stall for about 2 mins when checking fonts). No effect.
    Manually move out all Adobe folders in application support. No effect.
    Temporarily copy all Adobe folders from client X's home folder over. No effect.
    Create brand new home folder on the server, copy everything except fonts and preferences over from the old folder. No effect.
    Manually change all permissions to everyone RWX again. SEEMS to work!

Except now a week later, he's reporting the same problem again.

Looking through the logs doesn't reveal anything that looks out of the ordinary, though honestly I'm not even sure what to look for.

Btw, I did my troubleshooting after hours, when no one else was on the network, so I don't think it's a network congestion issue.

Are my macs possessed? Anyone have any idea what the heck is going on?
