You are installing software via group policy (e.g., a monitoring agent). You need to change the path to the source files for the install (due to server decommission, DFS deployment, etc.).
Per Microsoft, the only way to do this is with ADSI Edit:
- Open the Group Policy Management Console (gpmc.msc), expand Forest > Domains > your-domain > Group Policy Objects, and select the policy you want to update.
- Switch to the “Details” tab and note the “Unique ID” of the policy; you’ll need this momentarily.
- Open ADSI Edit (adsiedit.msc) and connect to the “Default naming context” for your domain.
- Expand CN=Packages,CN=Class Store,CN=Machine,CN=uniqe-id,CN=Policies,CN=System,DC=your,DC=domain
- There should be a single object (class “packageRegistration”); edit that object.
- Find the “msiFileList” attribute and edit it.
- Select the existing path and click “Remove”. This will remove that path from the list but also copy it into the “Value to add” field so that you can easily edit it (if, for example, the you’re just changing the hostname for the share but the rest of the path is the same).
- Edit/replace the path in the “Value to add” field and click the Add button. NOTE: the path will be prepended by an index (e.g. “0:”); this should stay unchanged. If you have paths to the install media, you can include each by incrementing the index as you add the paths.
- Click OK to save your changes.
Repeat those steps for each software-deploying policy in your domain.
