DCOM was unable to communicate with the computer <ESXi host>

[frinnst]

So we added an esxi host temporary to veeam b&r. Now i get these messages daily:

DCOM was unable to communicate with the computer <ip of esxi host> using any of the configured protocols; requested by PID 44a8 (C:\Program Files\Veeam\Backup and Replication\Backup\Veeam.Backup.Manager.exe).

The host has since been removed from the inventory but we still see the messages. I'm a bit confused - a DCOM connection attempt to an esxi host is doomed to fail. Has anybody seen this before?

Have you contacted our support team already? Thanks.

Same here since update of Veeam One 9.5 U4 (Win2016 german language)

Every minute a entry in system event log of an old rejected repository server

DCOM konnte mit keinem der konfigurierten Protokolle mit dem Computer "hostname" kommunizieren; angefordert von PID f38 (C:\Program Files\Veeam\Veeam ONE\Veeam ONE Monitor Server\VeeamDCS.exe).

Fredrik was able to resolve this by removing old hosts from Veeam B&R and rebooting the backup server. If this doesn't help in your case, I recommend contacting technical support for a closer look. Thanks!
