Installed a fresh 2019 standard server with Microsoft server backup (vm on a 2019 hyper-v server). Server was clean to boot with the normal warnings... Installed Active Directory and promoted to be an Active Directory Server. After the promotion we are getting the following error once during boot and at the start of a windows server backup. The backup actually completes and has been tested to restore successfully.
Event ID: 10000
Source: DistributedCOM
Event Data: Unable to start a DCOM Server: {9C38ED61-D565-4728-AEEE-C80952F0ECDE}. The error: "0" Happened while starting this command: C:\Windows\System32\vdsldr.exe -Embedding
Any ideas on what is going on? I have dealt with DCOM 10016 issues before and had to set permissions but this one is a little different. I was headed down the path that since the local administrator is not there anymore after promotion that it is a permissions/account issue somewhere but haven't found anything there.
Also, what is error: "0"?
