Dear All,
I have a problem with our Exchange 2019. This was migrated a few months before from an SBS 2008 server in two steps, to a temporary E2016 server and finally to 2019. The old SBS was the only DC, all the migration process has been done successfully with dcpromo, they are not using it for months. The old DC name was "SERVER", the new is "SRV-DC". Now after I had cleared it's old server's DNS entry from DNS the Exchange services had stopped and I cannot start them. I have found the old DC server under Active directory sites, and deleted it, and also found some entries in DNS, and cleared them too. Now, I can't find anything about the old DC server, everything looks fine, all diagnostics show me that the only DC is SRV-DC, but Exchange services still couldn't start, first of all, the AD topology service. I got no explained error messages just event id 7000 and 7009, which tells me that the service is not starting due to a timeout.
Please help me!
Exchange powershell is not working too. Only diagnostics, health manager, health manager recovery and search host controller service is running, nothing else! IPv6 is enabled, and I have already uninstalled the AV from the computer, restarted a few times but there's no solution.
