Account-specific (Error code -36) issue -- I'm stumped.

Question

Hello All:
I'm at my wits' end trying to figure this one out; I've searched the forums (and about half of the internet), but I haven't yet run across this particular scenario:
Client's Mac:
G4/500 running Mac OS X 10.3.9
(there are 6 other Macs in this office; no others are experiencing this problem)
Shared PC:
WinXP SP2 running on an older beige Gateway PIII box.
Shared folders set up (with sharing permissions verified thoroughly).
Problem
The client is unable to connect to shared folders on the WinXP box; every time she tries, she's presented with the error message:
[quote]The Finder cannot complete the operation because some data in (smb://IPA.DDR.ESS.HERE) could not be read or written.
(Error code -36).[/quote]
This happens no matter how I authenticate (using her creds or mine -- I'm a domain admin, so I should have access) when trying to connect from her admin account. However, I am able to connect to any shared volume on the same machine if I log in on another admin account on the Mac (even if I use her credentials).
Obviously, it's not a connectivity or hardware issue, since the same computer is connecting without a problem (using a different account). Also, none of the other Mac users are having this problem. All users are on the same subnet.
Here's what I've tried so far in my troubleshooting process:
1. I verified sharing setup and permissions on the WinXP volume;
2. I tested to ensure other Macs could see the share -- they all could;
3. I've run the Mac OS 10.3.9 Combo updater;
4. I've updated Symantec Antivirus on the WinXP box (per the recommendation of an artice; but clean dogs?never hurts);
5. I've searched high and low with Google.
Since I can get to it from other accounts on the same computer, I'm inclined to believe there's some sort of user preference file corruption (or some other account-specific problem).
Is there a .plist file in the user's account that could be removed (and allowed to rebuild) to restore connectivity to the shared volume? Or is there some sort of utility to "rebuild" a user account? ...or am I barking up the wrong tree here?
Any assistance would be most appreciated!

Answer 1

Thanks for the suggestion, Charles.
I eliminated hardware as a culprit early in the troubleshooting process, since internet connectivity was still robust.
I also thought that the Directory Access information may have been to blame; that's why I went so far as to do a combo updater (as a sort of "whack on the head" measure).
But when I was able to log on the same Mac using a different account and I did not experience the issue, I started looking at account-specific issues.
From what I understand, Directory Access (SMB inclusive) are system-wide settings affecting all user accounts. Given that assumption, I was thinking there might be some sort of user-specific preference file that might be to blame here, but I don't want to just start blowing out .plist files willy-nilly until I can obtain a better understanding of which one(s) might be at fault.
My fallback plan is to simply create a new account for the user and migrate all her information over folder-by-folder, but I'm hoping there's an easier fix (plus, I'm looking at this as an opportunity for a better understanding of user account structure).
