NCM and Windows Server 2016 Shares

Blog Post created by Delio Castillo on Dec 1, 2016

Recently we provisioned a Windows Server 2016 to be a Windows File Server using Nimble Storage Volumes with iSCSI as the storage.

 

On a reboot I noticed that all the file shares disappeared. After Googling the problem I came up with this KB https://support.microsoft.com/en-us/kb/870964. The problem seemed to be that the `Server` service had come up before the `Microsoft iSCSI Initiator Service` and it was unable to see the files to share.

 

To confirm that this was the problem, the first thing was to restart the `Server` service. After a few seconds all the shares reappeared correctly.

 

Now to make the solution permanent I had to make the `Server` service be dependent on the `Microsoft iSCSI Initiator Service`, but since I use `Nimble Connection Manager` to establish connections to iscsi the solution was to make the `Server` service dependent on `Nimble Connection Manager`

 

Here are the steps:

 

Find the dependencies for `LanManServer` service using :

 

C:\Users\administrator>sc qc lanmanserver
[SC] QueryServiceConfig SUCCESS


SERVICE_NAME: lanmanserver
        TYPE               : 20  WIN32_SHARE_PROCESS
        START_TYPE         : 2   AUTO_START
        ERROR_CONTROL      : 1   NORMAL
        BINARY_PATH_NAME   : C:\Windows\System32\svchost.exe -k smbsvcs
        LOAD_ORDER_GROUP   :
        TAG                : 0
        DISPLAY_NAME       : Server
        DEPENDENCIES       : SamSS
                           : Srv2
        SERVICE_START_NAME : LocalSystem

 

Under dependencies we have 2 services `SamSS`(Security Accounts Manager) and `Srv2`(Server SMB 2.xxx Driver). We need to add the `Nimble Connection Manager` to the dependencies. for that we use the command `sc config LanManServer depend=SamSS/Srv2/"Nimble Connection Service"` SamSS and Srv2 were already part of the dependencies, we just added the Nimble Connection Service.

 

C:\Users\administrator>sc config LanManServer depend=SamSS/Srv2/"Nimble Connection Service"
[SC] ChangeServiceConfig SUCCESS

 

And that is it. You can reboot your server and confirm that the shares are available upon reboot.
