On a shared file the last user to save will be the final version. You need sharepont to control this problem and regulate the users who are accessing a file at any given time. It is expensive but it is the way to do what you want.

Sharepoint won't allow sharing of an xsl. It will allow you to convert xsl into html. I am not sure what you are hoping to do but generally speaking a file cannot be edited by more than one person at a time without some service managing those changes. They can use a file then exit and then another can use it and exit and so on.

Here is a link to microsoft on sharepoint http://office.microsoft.com/en-us/sharepoint-server-help/convert-an-xml-file-to-a-web-page-HA010215482.aspx

Perhaps this will help you target you goal more specifically.

Good luck,
Holler if you need help.

I'm not sure but this problem is not NTFS permission. NTFS by default disallow using file by more that one person in "modify mode". I would check in that Excel sheet in "Tools -> Share workbook/sheet" if there is checked a box "Allow apply changes concurrently by multiple users" (it's my translation :) but there is only one check box) If it is enabled, just disable it, then users will have a message that "This document is read-only because someone (and they see user login) uses it".

Hope it helps

OK, as it is an Excel file office it will by default prevent sharing documents, so it must be set manually.

In Excel 2003 you can disable it as isiek posted

In Excel 2007/10 you go to Review and klick on share workbook it should not be marked

So it's happen to all excel sheets?

Even if you create a new file, right?

If so some Standard must have been set, normally I would set this with GPO. I never used it to set this option, so don't know if it's available though.
Check the applied GPO settings on the client (rsop.msc) or with GPO Manager on the server what is applied to the client.

You can use Microsoft's GPO templates for example Office 2010.
