The checks in this section are important when it is impossible to start, or establish any communication with, an Indexing service on a particular computer. This may be an Indexing service which has never been used, or one that was running successfully but now will not run at all.
Is the Indexing service running?
If the Indexing service appears to be running but does not respond, stop it and any remaining IndexBroker.exe and IndexServer.exe processes, and then restart the service.
Are the correct Indexing service files present on both the client and Indexing service?
Compare the Indexing service files with those on a known, working system, or with the kit to ensure they are the correct files and versions. The Indexing Service files are IndexBroker.exe, IndexBrokerPS.dll, IndexServer.exe, IndexServerPS.dll, and IndexClient.dll.
Have all the Indexing service files been registered?
There is no harm in registering the files again, even if they are already registered.
Register each pair of files in the order given.
IndexBroker.exe /regserver regsvr32 IndexBrokerPS.dll IndexServer.exe /regserver regsvr32 IndexServerPS.dll regsvr32 IndexClient.dll
Are the Indexing service settings correct?
Use the Administration Console to check the Indexing service settings.
