Event ID 1110 followed by Event 11728

I have a Windows 2003 Standard Edition Server R2 fully patched and and setup with security parameters as only a print server.

In my event log I'm seeing the following two events:  I have done research but nothing linking these two events together.  Only one logging onto server is admin via RDP.  

 ANY IDEAS?
