Hi, @Boopathi S
Thank you for posting in Microsoft Q&A forum.
The error message you are encountering indicates a violation of a primary key constraint in the SQL database, specifically for the CI_DocumentStore table. This typically occurs when there is an attempt to insert a record with a key that already exists in the database.
To resolve this issue, you may consider the following steps:
- Check for Existing Records: Verify if the key (in this case, 16777216) already exists in the CI_DocumentStore table. You can do this by running a SQL query to search for that specific key.
- Decline Updates: If the updates causing the issue are not required in your environment, you can decline them in WSUS to prevent them from synchronizing to Configuration Manager.
- Manual Distribution: If you need the updates and cannot wait for a fix, consider manually downloading and distributing them.
