202 - Wie funktioniert der Zugriff auf den Cloud Storage unter Windows?

Supported Windows versions

The Cloud Storage supports all officially released Windows versions starting with Windows 10 Version 2004. Other Windows versions could also work, but are no longer supported by the LRZ.

The connection of the file storage under Windows depends on whether the computer used is a member of the Active Directory domain ads.mwn.de and whether the computer is located within the Munich Scientific Network (MWN).

Windows computers within the ads.mwn.de domain

To connect to a file storage, click on "Computer" in Windows Explorer with the left mouse button in Windows 10. In the context menu that appears, select "Connect network drive" (step 1).

The "Connect network drive" dialog box opens. In the dialog a list of the still free drive letters appears, from which any one can be selected, as well as an input field for the "Folder". The share must be entered in this input field, i.e. \\nas.ads.mwn.de\<account_id> for the personal online storage (step 2).

After clicking on "Finish", the file storage will mount itself under the selected drive letter in the Explorer. Since the machine is a member of the Windows domain, there is no need to specify a password - the machine will use the login name as well as the automatically provided Kerberos tickets of the logged-in user to connect and authenticate to the file storage.

Connecting to network drive with Windows - step 1:

Windows 10:

Connecting to network drive with Windows - step 2:

Other Windows computers (outside the ads.mwn-domain).

If a Windows computer is not a member of the domain, a user ID as well as a password must be specified - in addition to the steps described above. The corresponding dialog appears automatically after clicking the "Finish" button. The user name is entered as "ADS\<identifier>" i.e. e.g. ADS\ne23mek.

The password corresponds to the password of the identifier. If desired, the connection can be re-established at the next login. Because the password is saved, you should use this option only on your own computers.

Windows computer outside the MWN

Your computer is located outside the Munich Scientific Network (MWN) and is accordingly not a member of the ads.mwn.de domain. To connect to the cloud storage, you have to proceed as follows:

1. Establish an LRZ VPN connection (→ http://www.lrz.de/services/netz/mobil/vpn) between your computer on the Internet and the MWN.
2. Performing the steps as described if you are inside the MWN.
3. Additionally select "Establish connection with other credentials".
4. After clicking the "Finish" button, a dialog will appear prompting you to enter a user ID as well as a password. For the user name, ADS\<lrz-identifier> must be entered, accordingly e.g. ADS\ne23mek. The password corresponds to the password belonging to your LRZ identifier. If desired, the connection can be re-established at the next login. Because the password is saved, you should use this option only on your own computers.

Disconnecting from network drive

In order to disconnect from the network drive, one clicks with the left mouse button in Windows Explorer on "Computer" in Windows 10. In the context menu that appears, select the "Disconnect network drive" item.

Connecting the network drive via the command line

With the help of the 'net use' command (in the Windows PowerShell), the following steps can also be executed in a batch file. The exact syntax can be retrieved with the command "net help use".

Example 1:

The network share is mounted using the drive letter "X:\". You can use command 'net use' to check which drive letter is already in use. The user name is entered as "ADS\<identifier>".

Example 2:

The network share is mounted under a free drive letter. Furthermore, a prompt for the password appears. The password is not displayed.
