Please try to run ExBPA to have a health scan.If there's no related error,then I think you need to rebuild Performance Counter Library valuescd \windows\system32lodctr /RAfter that, please reboot the server.If the problem still persists, then please check event log again and then post error event here.Also please verify if you have TCP Chimney, TCPA and RSS enabled. If yes, please disable it.Besides, please try to follow the methods below check the exchange search status.1) In Performance monitor add the "Full Crawl Mode Status Counter",this counter is stored in "MSExchange Search Indices". Select the user database and if the value is 1 that the database is still being crawled.2) Test-ExchangeSearch.More related information to share with you:How to manually rebuild Performance Counter Library valueshttp://support.microsoft.com/kb/300956/en-usRegards,Xiu

From "Performance Object",please click the drop list and then try to find "MSExchange Search Indices".4. "Select conters from list",please select "Full Crawl Mode Status".5.

Hi all,Finally I opened a PSS case, the method that can solve the issue is according to the following technet article. The index directories that are associated with all mailbox databases, are removed using the cmdlet, ResetSearchIndex.ps1 -all.
