Finder not connecting to NAS drive

Question

Hi all,
I've recently been having trouble connecting to my NAS drive. The drive shows up in the Finder sidebar, but when I try to connect, Finder just hangs and nothing happens.
I've attempted connecting via the CMD+K > enter IP address route, but same thing happens - it wont mount it. After rebooting the NAS, Finder can then connect, but attempting to connect not having rebooted the drive never works.
This has only recently become a problem, and there are only two things that spring to mind that could be the issue:
a) the drive is pretty much full. This isn't a problem per se, as I am now using a new backup drive, and just using this one as an archive which I use to retrieve old files from. Could the fact that it is full be causing a problem?
b) it was previously connected to a Netgear ProSafe 16 Gigabit Switch, but is now at the end of a chain of routers (the actual chain being NAS - Airport Extreme in bridge mode - Mac Mini Server running as DHCP server, with two other routers acting as wireless points on the network - Netgear WNR2000N and another Airport Extreme in bridge mode).
I have given the drive a static IP in the DHCP setup on snow leopard server, and this was all working fine before. It seems to be recently (since I moved it from the Netgear Switch to the new location) that it started playing up (although I can't be sure it started at the same time that I moved it, only that it started after I moved it...)
Like I said, it can be seen in Finder, but just hangs when attempting to connect (doesn't actually freeze Finder, just doesn't connect to drive).
Any advice? The NAS is a LinkStation Buffalo 6TB drive, working in RAID 1, and I have its IP Address properties set to automatically via DHCP (would setting this to disable and manually putting in the IP address potentially solve it?)
Thanks for any advice.
Steve

Answer 1

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in the Console window, look under User Diagnostic Reports for crash reports related to the process. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.
