Errors while copying form WIN XP SMB share

Question

Hello,
I do have a really strange problem. I do have a XP box with a SMB share and I could use them from my iMac - means I see the mount, could create a file there and so on. I have some dir's at the XP share and there are files with long names (more than 8+3, two dots etc.). At both machines I used the same user and password, security seems not to be the problem.
I can't copy the files from my iMac using the Finder nor using mucommander. I always get something like "file not found". Although I see the files and have permissions to copy them. Of course I could copy the files from XP-XP and it's working for some files with 8.3 filenames from OSX-XP. So I thought the problem are the unusal filenames.
But the unusal filenames work if I copy form XP to OSX. So I think the problem is an OS X side because if I enable a SMB share at the iMAC and if I copy the same directories form XP to OSX, all is working fine. I also tried to increase the IPRSTACKSIZE - but this had no effect.
Has anybody an idea? I thought I could the XP box standing around just sharing some directories without working on it Now I have to logon and initate the copy process from XP to OSX if I need some files at my iMac.
best regards and thanks in advance!

I updated the systems yesterday and that did absolutely no good.
The only way that I can get a file copied over to the Win2k3 network share is to give that user 'Delete' privileges, and this is what I am trying to avoid. We don't want our users having the ability to delete files off of our server, only read and write.
"Delete Files and Folders" and "Delete" are the two security privileges that I must enable before a connected user on a Mac can copy files to the network share.
