Hi guys,
we installed KB5037224 on a VM running EX2016CU23 with November2023SU (http://support.microsoft.com/kb/KB5032147). Healthchecker showed us no issues whatsoever. Standard procedures have been taken, as restart before running HU and deactivate the AV. Installing the HU worked as expected and there are no issues stated in Logs before running the needed restart >>All EXCH-services come up an all seems fine. Restarting the VM starts the hassle. VM comes up an Logon is possible. It takes about 1-2 minutes to get the machine stalled completely. Totally stalled. Ping works but other than that nothing. No way to extract information from eventlog remotely. We have never experienced any behavior like this before nor on any other box installing KB5037224. AV is TrendMicro WFBS and on top we are running Cisco DUO as 2FA method to secure OWA/ECP. Hybrid ist activated. Nothing else on that box... Any one here who as experienced any thing similar to that?
Cheers
Patrick
