I could be wrong but I think that the DCOM error is a red herring. If
you think that the DCOM error is causing this then please post the full
content of the error message, there are a million and one DCOM errors!
Are there any other errors logged when users try to logon?
So this reboot is happening when you try to logon to the domain? Can
you logon to the machines locally? I think this may be a permissions
issue on the root folder or on the %systemroot% folder and its
subfolders. Make sure that "Everybody" has permissions on these.
