Handle to PlugPlaySecurityObject was requested, over and over agai

Hi,

We're in the process of setting up two Windows Server 2008 machines, one to

be a web server and the other an SQL Server. Having enabled auditing on the

machines, the SQL Server is continually logging events such as that below, at

the rate of around 40 every 10 seconds. The process ID referred to is the

DCOM Launcher (svchost.exe -k DcomLaunch). Is there any way to discover why

so many events are being generated and, ideally, stop them being generated?

Thanks,

Adam
