File shares on iSCSI devices may not be re-created when you restart the computer
This article provides a resolution to an issue that may prevent file shares from being re-created when you restart the computer.
Original product version: Windows 10 - all editions, Windows Server 2012 R2
Original KB number: 870964
You use the Microsoft iSCSI Initiator service to connect to an Internet SCSI (iSCSI) disk device. The file shares that you create for folders that are located on your iSCSI device may not be re-created when you restart the computer that the shares are created on.
The issue may occur when the iSCSI Initiator service isn't initialized when the Server service initializes. The Server service creates file shares. However, because iSCSI disk devices aren't available, the Server service can't create file shares for iSCSI devices until the iSCSI service is initialized.
iSCSI Initiator 2.x
To resolve the issue in iSCSI Initiator 2.x, follow these steps on the affected server:
- Make the Server service dependent on the iSCSI Initiator service. For information about how to do this, see the "Make the Server service dependent on the iSCSI Initiator service" section.
- Configure persistent logons to the target. To do this, use one of the following methods.
If you see the target on the Persistent Target tab, the following steps are not required.
Method 1: Use the iSCSI Initiator in Control Panel
- In Control Panel, double-click iSCSI Initiator.
- Select the Targets tab.
- Select a target in the Select a target list, and then select Log On.
- Select to select the Automatically restore this connection when the system boots check box, and then select OK. Method 2: Use the Command Prompt window
- Select Start, select Run, type cmd, and then select OK.
- At the command prompt, type the following command, and then press ENTER: iscsicli persistentlogintarget target_iqn T * * * * * * * * * * * * * * * 0
target_iqn is the IQN name of the target. 3. Configure the BindPersistentVolumes option for the iSCSI Initiator service. To do this, use one of the following methods.
Method 1: Use the iSCSI Initiator in Control Panel
In Control Panel, double-click iSCSI Initiator.
Select the Bound Volumes/Devices tab.
Select Bind All to bind all the persistent targets. Or, select Add, and then enter a drive letter or mount point to bind a specific target.
Select OK. Method 2: Use the Command Prompt window
Select Start, select Run, type cmd, and then press ENTER.
Type iscsicli BindPersistentVolumes, and then press ENTER.
This is the same as selecting the Bind All option in Method 1.> [!NOTE] Use this resolution only if you experience this specific issue with version 2.x of the iSCSI Initiator service.
Make the Server service dependent on the iSCSI Initiator service
Use one of the following methods to make the Server service dependent on the iSCSI Initiator service.
Method 1: Use the Microsoft Service Control utility (Sc.exe)
You do not have to modify the registry when you use this method. Therefore, this method is the preferred way to set the service dependency.
- Click Start, click Run, type cmd, and then press ENTER.
- Type sc config LanManServer depend= Samss/Srv/MSiSCSI, and then press ENTER.
If you have administrative access to the server, you can run this command from a network computer. Type the following command, and then press ENTER: sc \ computer_name config LanManServer depend= Samss/Srv/MSiSCSI
Method 2: Use Registry Editor
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows
Microsoft Windows 2000
Start Registry Editor.
Locate and then click the following registry subkey:
On the Edit menu, click Add Value.
Type DependOnService in the Value Name box, click REG_MULTI_SZ in the Data Type box, and then press ENTER.
In the Multi-String Editor window, type MSiSCSI in the data box, and then click OK.
Exit Registry Editor.
You can script the procedures that are described in the "Resolution" section by using the Sc.exe and Iscsicli.exe utilities. To do this, create a batch file that uses these commands, and then either run the batch file directly, or run the batch file in another way. For example, run the batch file by using Group Policy.

This article assumes that you're familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure. However, they won't modify these examples to provide added functionality or construct procedures to meet your specific requirements.
To script the whole operation that is described in the "Resolution" section, create a batch file that contains the following text:
sc config LanManServer depend= Samss/Srv/MSiSCSI iscsicli BindPersistentVolumes
The issue could also happen to non-iscsi storage if server service is started before the storage has been initialized. In that case, we can use the below workaround, assuming G is the drive letter we want to monitor:
- Save the script as a *.bat file.
:Start dir G: /AH if %errorlevel% equ 0 goto :OK ping 127.0.0.1 /n 5 goto :Start :OK net stop browser net stop netlogon net stop dfs net stop lanmanserver /y net start lanmanserver net start dfs net start netlogon net start browser
- We can add the bat file to "Start Script": a) Put the batch file into %systemroot%\System32\GroupPolicy\Machine\Scripts\Startup b) Run "gpedit" to open local computer policy c) Add the batch file into the startup script.
