SYMPTOMS
When you start Microsoft Windows Storage Server 2003, if the Windows-based computer cannot obtain a valid IP address, the User Name Mapping service does not start.

Additionally, the following error messages appear in the application event log:

Event ID 8278 :User Name Mapping failed to register the following version and protocol with the portmapper : 1 TCP. You will need to restart User Name Mapping for client programs to be able to communicate with the service.

Event ID 8278 :User Name Mapping failed to register the following version and protocol with the portmapper : 1 UDP. You will need to restart User Name Mapping for client programs to be able to communicate with the service.

Event ID 8278 :User Name Mapping failed to register the following version and protocol with the portmapper : 2 TCP. You will need to restart User Name Mapping for client programs to be able to communicate with the service.

Event ID 8278 :User Name Mapping failed to register the following version and protocol with the portmapper : 2 UDP. You will need to restart User Name Mapping for client programs to be able to communicate with the service.

Although the exact Event ID may vary, these errors occur on any Windows-based operating system that has any one of the versions of Microsoft Windows Services for UNIX that are listed in the &quot;applies to&quot; section of this article.



CAUSE
These errors occur because the User Name Mapping service is dependent on the network connectivity; the service must have at least one network connection to start.

These errors do not affect the system, and the User Name Mapping service will work as expected after the system has a valid IP address.



RESOLUTION
Make sure that the Windows-based computer has a valid IP address, and then manually restart the User Name Mapping service.
