Air-Gap System Deployment
Everything I've read indicated that MCC must be deployed on an Internet connected system. However, Microsoft Copolite said it can be deployed on an air-gap (i.e. closed, non-Internet facing) system and to use the pre-seeding tool to download contents. My main interest is to use MCC to assist with future Windows OS upgrade and (secondary) patching on my closed network. I currently pull-down patches via a connected WSUS and then sneakernet them over to the WSUS servers on our closed networks. Has anyone successfully deployed MCC in an air-gap environment and operating as intended? Any lessons learned? Thanks in advance.
Waiting for MCC container to become available
Hi, Trying to setup Intune Connected Cache and getting stuck on MCC Install Waiting for MCC container to become available. running on Server 2022 VM with nested virtulization turned on and using a groupMSA account. I have set this up fine on one of our other domains\tenancy. Any ideas? Tried starting from scratch several times and not sure whats stopping it. Thanks ScottCache server hostname source & LocalPolicyMerge setting
hi In our organization we have the LocalPolicyMerge setting set to false thus blocking all standard or custom locally created inbound MDE firewall rule. Outbound does not have any such restriction. We do see that the clients does not receive OptionID235 value from DHCP server. We did see a note in the Microsoft documentation [Delivery Optimization reference] been called out for this, but with less information on what is the configuration or setting that gets blocked. If the LocalPolicyMerge setting is configured, such as part of security baselines, it can impact DHCP client and prevent it from retrieving this DHCP option, especially in Autopilot scenarios. Does anyone have the same issue and what are the rules that were created to have this working? Thank you.MCC Phantom Install

Stuck on "MCC container detected as running, waiting for MCC to return ready status code"
Hi all, We’ve followed Microsoft’s guide to set up Microsoft Connected Cache, but we’re hitting a roadblock. When attempting to deploy the cache node, the process gets stuck at the following message: "MCC container detected as running, waiting for MCC to return ready status code" It doesn’t move past this point. We haven’t been able to find any clear documentation or community guidance on what this specific status means or how to troubleshoot it. Has anyone else run into this issue, and if so, how did you resolve it? Thanks in advance for any help,generateCsr.sh failing
