Issue/Introduction
We had installed UIM version 20.1 in windows platform 2016. Now we are facing issue like unable to activate SLM and service type probes. We are unable to send QOS data to the database and this is impacting our SLA and unable to get any report as well.
We are getting like below errors in data_engine probe :--

Most of the probes on the Primary hub were red and all of the probe logs stopped being written to on Sep 15 at 13:56
UIM had been running fine for 2 months since the upgrade. Then all of a sudden the slm related services and other probes went down/turned red.
- distsrv and other probe logs show a complete stoppage at Sep 20 15:56:51:482 [4008] 1 distsrv: RequestQueueCleanup.
- NONE of the probe logs were being written to disk.
- Disks on the Primary hub were not full nor near full
All other hubs operating fine except the Primary

Environment
Release : 20.1
Component : UIM - INSTALL
Cause
- Sep 20 at 13:56 there was a change to the Windows machine configuration
Resolution
ping cluster ip and nodes, no issue. telnet at port worked fine as well.
telnet to cluster VIP at port worked fine as well.
RDP as the service account user:
'Error: The connection was denied because the user account is not authorized for remote login'
As it turns out, someone/some process/policy change removed the Service Account from the Windows Administrators Group.
After the service account-> xxxxx\<SERVICE_USER_ID> was re-added into the Windows Administrators Group on the local machine, and the Primary hub was restarted, the hub and all of its probes started working as expected again.
The Primary hub robot was running as that same Windows service account and the data_engine database user was configured as that same account.
