[File system repository] Authentication problem

Hi All,

I create a file system repository which link to local windows2003 file system.

The Security Manger: W2kSecurityManager

I also setup user mapping for windows system with the user "epprd.mycompany.com\administrator".

In the content administrator-> KM content

If i click the "edit locally" at the context menu which locate on the right side of the office file , I can modify the file.

Now, there is a problem.

When i "click" the office file(word, excel ,...) , it ask me for input user id and password.

Whether i input the correct user ID and password or not, i can't modify the file.

Anyone have any idea about this issue.

The system is EP7 SP14.

OS: window 2003
