Hi,

We are having a persistant problem that is really hard to fix. We have a windows 2000 file server that has a few shares on it. There are many users that connect to this share. Windows XP, Mac 10.3.8, 10.4.6, etc etc. Here are the facts and the problem:

Facts:
There is a windows 2000 domain controller. All users have accounts on this.
The file server is a different windows 2000 machine.
All of the shares on the file server are open to the world (we have a firewall)
but users often authenticate with their Windows login anyway to start smb sessions to the file server.
Appletalk is turned off on both the DC and file server.
All users can connect to the file server and mount shares without any problems.
They can read files off of the shares no problem.
All users can write "small files" to the file server no problem.
PC users can write huge files with no problems.

Problem:
Macitosh users (10.3 and 10.4) can start sending large files (>200MB) to the network share, and they will speedily write the entire file, but they will always timeout at the last file MB, and eventually, the machine will throw an error code -36, which is a generic I/O error. This is reproducable.

I have seen this error described often but never solved. I have turned on the network DDE and network DDE DSDM services, I have tried other things. Any suggestions?

-Jeff

How is/are the volumes containg the shares formatted (FAT32 or NTFS)? Are there any illegal characters in the filenames that the Mac users are trying to transfer?
I do not like those green links and spam.

NTFS, no funny chars. And in addition to that, no super long pathnames as well. Pretty consistent. I have had a few "me too" resonses in other forums. This is obviously a problem. Any other solutions?

The only time I encountered this was a network that had an NT server with a bunch of Macs running 10.2.x, and it was with long pathnames (files buried several folders deep). At that time, someone suggested DAVE as a solution but I never tried it. Maybe you could download the trial version and see if it helps.

That is not the problem. We have tried to write to the top level of the share as well. This problem is very reproducable. I cant believe we are the only ones experiencing this.

It may still be worth trying DAVE. You can download a demo to see if it works, so there's nothing to lose.
