So if some of your workstations are not showing up properly in the SBS 2008 Computers console, here’s what I did to fix all of my truant ones.
Event ID 10016 Source DCOM:
In my case I went into Dcomcnfg.exe
Then I went under component services, computers, my computer, dcom config, then found the 49BD2028-1523-11D1-AD79-00C04FD8FDFF CSLID and changed the settings to “use default”
Then I followed this and
Repairing and re-registering the WMI:
Did the following commands at a c:\
rundll32 wbemupgd, UpgradeRepository
Then did this:
This big square box will load up just hit cancel.
Close the command window.
Why did I do all of that? to get the WMI kicked back into gear so I could fix the lack of security status being reported in the SBS 2008 console.
If your machines are not checking in, it’s either a firewall blocking the communication, or your WMI messed up.
Vista and Win7′s were connecting just fine but I had three XPs not reporting the proper security status. Remember that servers will not report a status as they have no security status center.
