[08/11/2025 14:45:26] MCC install has completed within WSL Ubuntu distroSolvedmarty5Dec 10, 2025Brass Contributor383Views0likes4CommentsQuestion regarding update requests on the MCC node
So, as I have understood it, the MCC requires an update request to be requested 3 times by different devices before it actually starts to download it to cache it. 1. How many downloads does the MCC node download at the same time? 2. Does the MCC node keep a que list? 3. Does an update request ever "time out" on the MCC node or is it kept forever until reaching 3? What we have seen on the lab with 10 laptops, it is struggling to get more than 20% updates distributed from the MCC node. We re-install the laptops with the same USB installer multiple times when Windows reports it to be updated, so all of them are installed on the same build level every time. 4. How many times do we need to "re-install" windows until all updates are cached?MakkyDec 09, 2025Copper Contributor10Views0likes0CommentsCheck cache status on MCC node
Is it posssible to check/monitor the amount of data the MCC node has cached? Since the MCC downloads updates only when requested 3x by the clients, it would be good to know how much % of an update is actually cached. This would give the most value when troubleshooting the MCC and the distribution of updates. We have configured a MCC in our LAB with 10 connected clients, and the amount of data shared varies too much for each client.MakkyDec 03, 2025Copper Contributor18Views1like0CommentsMCC Container missing mount points - unable to get CSR
MCC for Enterprise installed on Server 2022 I have around 20 nearly identical servers set up with MS Connected Cache, but two of them refuse to deploy the container in a fully operational state. Everything works perfectly fine over port 80. However, when I run the generateCSR.ps1 script, it fails. After digging around for quite a while, I found that the mount point inside the container is missing. This means that although the CSR is being generated, it can't send it back to Ubuntu and then to Windows. Running the 'docker inspect MCC' command yields this result: But, it's supposed to look like this: Apparently, you can't just add a mount point to the container. It has to be removed and redeployed with the mount point specified. However, I'm not able to figure out any way of doing that since the script seems to be deploying the container in a way that it generates the configuration file when running the deployment script instead of me being able to modify it for the deployment. I'm at a bit of a loss as to how to fix this or why it's even happening. I've already tried ripping everything out, including WSL and Hyper-V, and redeploying, with no success. Thoughts?jjmehrenNov 26, 2025Copper Contributor30Views0likes1CommentCache node successfully deployed but not serving requests
Hello All, I have successfully deployed Cache node on a Windows 11 Entra ID joined PCs in two locations. Both Cache nodes are showing healthy, and Intune policy with DOCacheHost was successful. However Cache node is not serving client requests. I have checked all troubleshooting steps that MS mentioned in the below article. Everything looks normal. https://learn.microsoft.com/en-us/windows/deployment/do/mcc-ent-troubleshooting 1. I ran "DeliveryOptimizationTroubleshooter" It is showing below unable to make WebRequest using MCC link over port 80 under "MCC DEVICE SETUP" 2. As per the troubleshooting document, I do not see any errors on port forwarding rules: 3. In both locations its the same behaviour, no FW between MCC Cache node to the Client PC, both are in same network. I have tried disabling windows FW on both ends. no luck. 4. Also command "netsh -a" results on MCC shows it is listening to port 80 I know it is something to tweak about networks, but not sure what i am missing as there is no NW FW/Windows FW, but why Client is failing on http://:80 and any idea?Sreekanth_ReddyNov 19, 2025Copper Contributor249Views0likes2CommentsMCC Install Failure - Code 13631746

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.myyodamailOct 03, 2025Copper Contributor47Views0likes0CommentsWaiting 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 Scottscottu1615Oct 01, 2025Copper Contributor643Views0likes7CommentsCache 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.bindumadhavaSep 26, 2025Brass Contributor92Views0likes1Comment
