SharePoint Search Service is not working

I am using SharePoint Server 2007 with collaboration portal template on Windows Server 2008. When I use the following function from Central Administration from Application Management -> search -> Manage Search Service, I met with the following error message, any ideas what is wrong?

The search service is currently offline. Visit the 开发者_如何学编程Services on Server page in SharePoint Central Administration to verify whether the service is enabled. This might also be because an indexer move is in progress.

thanks in advance, George

This can happen for a variety of reasons. e.g. Search is infact moving/setting up the indexer, patch levels are different in the farm, etc. Rather than attempt to list all and their fixes, please see the links below:

I would suggest to start with the Event Logs on your Indexer. Also cross check your event logs with the Query servers.

Typically, if something is wrong, it would be logged there (or the ULS logs). But in this case start with the Event VWR... and reset search service on the indexer as well (using Service.msc)
