Hi, I'd be happy to help you out with your question. Sorry for the inconvenience caused. To address your issue, I recommend exploring the following solutions: Consider setting up a proxy server that allows traffic to specific IP addresses or FQDNs for Windows Update servers. This will enable your servers to access the internet while maintaining the necessary security protocols. Microsoft offers offline updates that can be manually downloaded and installed on your servers. This involves downloading the updates on a separate machine with internet access, and then transferring them to your servers via USB or other removable media. If your current version of WSUS is unreliable and consuming too much space, I recommend upgrading to the latest version. The latest version includes improvements that can help reduce the amount of disk space required and improve reliability. If you have any other questions or need assistance with anything, please don't hesitate to let me know. I'm here to help.
