I have been getting hundreds of DCOM errors in my SBS 2011 System log, I believe attributed to NIS 2013 on my client workstation units. Uninstalling NIS 2013 from two of the workstation units, removed the errors associated with the errors for each of those units from the log. Reinstalling the NIS 2013 back to the workstations brought back the error messages. I don't like this solution, as it means removing NIS 2013 from my client workstations to clear the error log. Adjusting the network and web settings within NIS 2013 on the workstations and policy/security policy settings within the SBS 2011 has not helped, however I do not believe I have exhausted the amount of settings involved. Any suggestions
