When adding multiple shares, it’s possible that you may get an error message similar to the
Troubleshooting - Multiple Shares
This is caused by having multiple shares to the same resource using different credentials. The
error occurs when connecting to at least one secure, restricted share. Due to a constraint
in Microsoft Windows only one set of credentials can map drive letters to a network resource
such as the LinkStation. Thus, only one username and password can be used while mapping
to your LinkStation, even if different drive letters are mapped to different shares. If unsecure,
unrestricted shares are mapped, and then an attempt to map a secure, restricted share occurs,
this error will occur. To remedy the situation, you must create all shares using the same login
and password information. Please follow the steps on the next page to remedy this problem.
