this file start work by himself and sometimes it starts more then one time at one. it's wouldnt bother me, if it didnt take 100% of processor resourses... everytime I end task it, but still it start again..

ok, if someone interesting: http://www.anzdl.com/srchadm/help/filtrhlp.htm The CiDaemon process is a child process created by the Microsoft Index Server engine. The Index Server engine gives a list of documents to the CiDaemon process and it is responsible for filtering the documents by identifying the correct filter DLL and word-breaker DLL associated with a specific document. Filtering is done as a background activity so as not to interfere with any foreground activity. On local drives, if a document opened by the CiDaemon process for reading is needed by another process for writing, the CiDaemon process closes the document as soon as possible. The document will be retried for filtering at a later time. (This feature is not available on network shares.) If the CiDaemon process stops, it will be automatically restarted by the Index Server engine.

shold there be more than one instance of this running at the same time? On my server there are 5 instances of cidaemon.exe running.

Well, ralph, according to Microsoft - it is. Though not saying this explicitly, it is *definitely* legal to have more than one 'svchost.exe' up and running at the same time, and since cidaemon.exe is actually a child process of svchost.exe (at least I believe so) - I think Index Service Engine is, too - it is possible to have more of them started. Why would you need, say, 5 instances of the same service? Let's just say it has a lot to do with multithreading - it's more effective from the processor-time point of view (especially if your server is SMP-based, but this works for uniprocessor systems as well). Check it out for yourself at http://support.microsoft.com/support/kb/articles/Q250/3/20.ASP , though I warn you that the information provided therein is very scarce & technical (as we could expect more from Microsoft :-(( )

ONe way to fix it: turn off indexing right click my computer>manage click services right click "indexing service" then click stop now, right click indexing servie>properties. click the "Automatic" tab. make it say MANUAL (not disabled) . then apply. This will not bother you any more! cheers.

yay thanks you got rid of all 5 ci demons!colin
