Following on from the LRS Internal updater server blog post i wanted to give me details in what i found when trying to use WSUS with LRS’s.
It appears although WSUS is allowed to be configured in the LRS and SMARTs documentation and Microsoft KB mentions using WSUS but it seems the LRS wont use WSUS even if you configure it to!!!
LRS have two updates
- Microsoft Updates
- OEM Updates (SMART, Polycom, Cestron)
There are two ways to apply each update
- OEM and Microsoft Update Server (Online)
- Internal Update Server (Offline)
OEM and Microsoft Update Server (Online)
If you allow your LRS internet access either directly or through a proxy server the LRS will download and install its updates from Microsoft Update server and from an OEMs update Server so job done.
This relies on the LRS being allowed to access and be able to download its updates. In some scenarios and customer environments this is not allowed so you need to setup an internal update server to provide updates for the LRSs without internet access.
Internal Update Server (Offline)
In the case where allowing your LRS internet access is not an option you should set up an internal server on your network and manually download the update files from the OEM to an internal server using IIS and configure the LRS to download its updates from the Server. (If you need to deploy one check out my blog post)
But what about WSUS Server for my Microsoft Updates !
BUT what about the Microsoft Updates and the option to use an internal WSUS for the Microsoft Updates!!!!
Your first thoughts are ok i need to point the LRS to a WSUS Server to get the Microsoft Updates for Windows 7 embedded as documentation mentions this can be used.
I found that if you configure the LRS to point to the WSUS Server http:\\wsusserver:8530 the LRS never reports into WSUS even after a restart. I tested the LRS connection to WSUS via cmd and internet explorer and it worked ok.
I checked the registry on the LRS for Windows Update settings under
and found that although WSUS was configured and enabled the registry key values were in fact set to NOT use a WSUS server!
AUOptions – 0
NoAutoUpdate – 1
I did mange to modify the registry and get the LRS to report into WSUS but i wont mentions what i did as if you read on you shouldnt use WSUS it seems.
This made me think perhaps this is by design, i decided to look into the update package downloaded from SMART to see if any Microsoft OS updates are included in there and yes they are. particularly update 15.12.1 where they 34 updates.
I checked the SMART documentation again and its mentioned you can configure WSUS and to check i wasnt going crazy.
and the Microsoft CU KB mentions WSUS under Intranet Server Updates as well.
When you think also as the LRS is an appliance how do you know what Microsoft Updates approved and are supported for the LRS to not break it ?????
I reached out to SMART and im waiting for updated documentation on this as i found it very confusing and spent ages on this for something that appears not be needed / should be used.
SO my understanding now is that when you use an internal Update Server to apply the OEM update this ALSO applies the Microsoft updates! and you should not configure the LRS to use WSUS.
I did however find on the Cestron Site a PDF that confirms my findings
Note: The “Microsoft Updates” section does not need to be set and is overridden by the “OEM Updates” section
What id like to see now is updated documentation from SMART and Microsoft to confirm this. Perhaps WSUS has been left in the LRS settings for the future maybe but for not its confusing !
