Try the following 1) Try and apply latest service packs for Exchange and NT 2) You might need to reinstall your exchange. Note: reinstalling does not affect any of your databases or settings. 3) If all else fails backup up your databases and do a clean install Good Luck -----Original Message----- From: A.L Paul [mailto:alikanza@xxxxxxxxxxx] Sent: Thursday, April 08, 2004 7:43 AM To: [ExchangeList] Subject: [exchangelist] System services http://www.MSExchange.org/ Hi all,im having some trouble starting the MS System monitor service on my server(NT 4.0 exchange 5.5).It returns the error: "Procedure entry point SymGetLineFromAddr could not be located in the dynamic link Librady IMAGEHLP.dll" Then when I click ok,it attempts to start the service but returns error: "MS System Monitor Service returned service specific error 100" Anyone had such a setback,any ideas on the way forward?
