Hi, I have a windows cluster files based on dfs. On my Windows XP client, net use was working corretly. But now with Win7 I have trouble: I can map a folder using net use but then I'm unable to create a file in the folder. I have the message " S: refer to a location that is unavailable...." If I try toc reate the file trough the cmd it's working. And If I try to create the file via Windows XP it also working. Any idea ?

How does it work if you manually map the folder? Did you map the folder with startup script? If so, I suggest you read the following article.
