Thanks, but thats not it. Could there be (an)other cause(s)? and is it ok

for this dll to be running - what are the potential pitfalls?

Here's some info.."dllhost is the host process for all COM+ applications.
--------------------------------------------------------------------
DCOM support module for DLL based COM objects (DCOM = Distributed Component
Object Model). DCOM is a software architecture model which is an intrinsic
part of Windows, of most Microsoft products, and of many non-Microsoft
products. In most cases you should never see DLLHOST in your Task List, as,
typically, DLLHOST starts, does what it has to do, and then terminates.
However, sometimes, if a Java COM object runs (this could happen if you are
browsing the Internet and come to a page which has Java code), DLLHOST may
not terminate, which is when you would see it in your Task
List.Recommendation : Do not ""End Task"" it as there is no way to determine
whether DLLHOST has completed its task or not. For the more advanced users,
however, deleting the registry key ""HKEY_LOCAL_MACHINE\SOFTWARE\
Microsoft\Java VM\MSDebug"" can often solve the problem of DLLHOST
constantly appearing in the Task List
