Kerberos KDC Errors
Hello, I have been testing Windows Server 2025 with AD DC role and sometimes in event log I can see error. The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was and lookup type 0x108. Just a note - I did not remove the account name; it is not just there, not even once. I'm unable to connect it to some "action", so it looks a bit random. In data field there is only C000000D (in words) which is every time the same. Event ID is 7. Is this okay or anything to worry about?

Server 2025 Hotpatching | Windows Azure Arc VMs
Hello! I was trying to test Hotpatching with an on-prem Server 2025 Standard. It has Azure Arc installed on it, but when I tried to apply a Hotpatching policy in Azure, it said the VM was not supported. On-prem VMs with Azure Arc will have Hotpatching Support, correct?RAM Memory Leak Issue
Good morning. I am experiencing issues with an updated installation of Windows Server 2016. The task manager reports 8.1GB of memory used (which normally tends to grow indefinitely), and I can't figure out what is using this memory. The growth is about 1GB per day. However, no processes appear that justify the 8GB of RAM used. Even using RAMMAP, I can't find anything significant... On the server, additionally, we have SentinelOne as antivirus and Apache-Tomcat. Thank you for your help.Problems to join Debian/Ubuntu machines to a domain
