I just installed a new SBS 2011 Standard server – migrating to this from an operational SBS 2003 Server.
Both servers have firewall disabled. Both servers and all PC’s are on the same local subnet.
From when this new server was brought online, periodically through the day I get repeating System Event ID 10009 with the verbiage, “DCOM was unable to communicate with the computer [FQDN of many PC’s] using any of the configured protocols.”
Again, firewalls are disabled and the listed PC’s are in the Domain and powered-up.
Any help will be appreciated.
