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? Paul.
