Folder access privileges on remote drive

Can you please be more specific?

Do you really have an iMac G5?
Because Mac OS X 10.6 (Snow Leopard) will not run on that.

Have a look at System Profiler > Hardware Overview to see what Mac you use and at About This Mac what Mac OS X version you run.





Also what kind of network do you use?

Have you right clicked on those folders to see what permissions are set for them?



What other Macs and PCs do you have this problem with?



The following is taken from the thread titled "How to maximise your MacRumors troubleshooting experience" created by mad jew in 2006. It contains more elaborate information on the short extracts I took from it and should help you in finding appropriate help. I also made some additions after finding that thread.

1. Search for threads or guides containing similar problems.
   MRoogle is quite a good tool to search these forums.
   
2. Start your thread in the appropriate forum or sub-forum.
   Here is the forum's main page with the list of all the sub-fora found here.
   
   [*]Use a specific thread title.
   "Need help!!!!???? ASAP!!!" and its variants are not specific.
   
3. Find and post machine hardware and software configurations.
   You can find out more about your Mac by going to the Menu Bar > > About This Mac > More Info ... (this button opens Applications / Utilities / System Profiler) > Hardware Overview.
   
4. Tell us your problem, and be specific. What is happening to your machine?
   
5. How long has this been happening? What changes were made just before this started?
   
6. What have you already tried?
   
7. Respond to all posted advice with details of what happened.
   
8. Be wary of the (very) occasional bad advice.
   
9. Be patient.
   
10. Be courteous.
