Errors during file transfer on WebDav server

Question

(this is a repost from a different category)
I having much difficulty transferring files to and from our new WebDav server when using Finder's Connect to Server. I am able to connect and authenticate just fine. Although, when dragging and dropping to a mounted drive, I receive the following errors, then subsequently dropped from the sever.
...Unexpected Error Occurred - Error code 1407
...cannot comple the operation because some data in "" could not be read or written - Error code 36
...Unexpected Error Occurred - Error code 1407
This seems to be an issue affecting all 10.5 users in our university. PC's and 10.4 do not seem to be having this issue. When using CyberDuck and Goliath, I cannot login to the server whatsoever.
Any thoughts?

These remind me why I like to use ProcMon to correlate and supplement
all log messages. 
FWIW I agree that clearing your SoftwareDistribution folder might change this aspect of your symptom description from setupact.log

It is really difficult "reading between the lines" to understand that one but I imagine it would be a lot easier having a ProcMon trace which showed exactly which file was "not found" (and whether it was the same one or a different one each time).
