Thanks for the response: Note: The server and domain are both completely isolated from the outside world. (Classified environment). I have no other WSUS server to sync.
I was looking for a solution to download just the defender definitions/updates and somehow import them into the off-line WSUS. Is that possible?
I download the WsusContent and metadata from my unclassified computer to Blu-Ray each month and import the Blu-ray into the off-line classified WSUS server.
All the articles I have found all talk about and assume the WSUS box is on-line connected to Microsoft. The off-line articles all talk about getting the monthly metadata, but they don't talk about weekly defender updates. Any suggestions!!
