The Micro Update Service allows records (e.g. User, Apps, Devices) to be updated from an external process (e.g. SCCM build script) by reading micro update files from a shared location. This allows business tools to update ManagementStudio without any knowledge of the  MS API.


MUS Service requires MS version 2022.0.8.5 or higher





The system requires a correctly constructed text file to be placed in one of the folders that the service monitors. 


The file should:

  • Start with: MUS_
  • Be a unique filename - See note below.
  • Content should identify a ManagementStudio record
  • Content should identify at least one field or custom field ID (More than one is OK, but each requires a line)


E.g. The filename MUS_DT113421_01.txt is a valid filename

  • Starts with MUS_ 
  • Has computer name in the file name
  • Has a   _01  at the end to make this instance of the file name unique, DateTime could also be used to make it unique.
Unique file names are not a requirement, however processed files are stored for later inspection, if they have the same filename they will overwrite previous versions of the file.



If there are multiple projects and therefore multiple versions of the Micro Update Service operational it is important that they monitor different folders.

i.e.

               \\Servername\Share\ProjectName               \\DataServer01\Incoming\MergerProject

               \\Servername\Share\ProjectName               \\DataServer01\Incoming\HardwareRefreshProject



SCCM Command-Line to generate a file on a share

cmd.exe /c "(echo ID:Hostname:%COMPUTERNAME% & echo CFId:100:Upgrade Initiated & echo CFId:110:Task Sequence Completed)> \\ServerName\Share\MUS_%COMPUTERNAME%.txt"


SCCM Sample including the time in the file name

cmd.exe /c "(echo ID:Hostname:%COMPUTERNAME% & echo CFId:100:Upgrade Initiated & echo CFId:110:Task Sequence Completed)> \\ServerName\Share\MUS_%COMPUTERNAME%_%time:~1,1%%time:~3,2%%time:~6,2%.txt"



The first line of the text file should identify the ManagementStudio object that will be updated

using the ID prefix and the line must contain the Target Type and the Name or Value of that target.


ID:IdType:TargetName


Subsequent lines should contain The target type followed by the target followed by the value


TargetType:Target:NewValue

IDAppId, MigrationId, Hostname.. etce.g. 1000, 'PC0001', 'global\rhynes'
FieldAppVendor, AppName, FirstName.. etc
CFPathCF Path e.g. 'Form\Section\Field'
CFIdCF Field Id e.g. 1234

Special Characters. ':' and 'new line' characters can't normally be used in the 'Value' portion of the micro update and need to be escaped.
To add a ':' use '\:' and to add a new line use '\n'.


Exmaple Text files


Ex - Update Devices from SCCM TS

ID:Hostname:PC00045

CFId:14801:True

CFId:14802:This is the error message from the task sequence


ID:MigrationID:8901

CFId:153:ThisData2`r`nThatData2`r`nMoreData8


Ex - Update a User 

ID : SamAccount : global\jdoe

Field: Email: jdoe@global.com


Ex - Create a new App and move it to a Process

Id: App-CustomerId: 12345

Option: CreateIfNotFound: true

Field: AppVendor: Adobe

Field: AppName: New Reader

Field: AppVersion:2021.011.20039

Process: Process: Process:2. Discovery

Security

As MangementStudio will be reading anonymous text files from a share and using this to change data it is important to permission the share so that only AD accounts that you want to be able to update ManagementStudio have permission to write to this share. 

i.e. If the MUS is being used to read updates from an SCCM TS then only the SCCM AD account and the ManagementStudio account should have write access to that share.
