Hello,

I am using log parser 2.2 for copying my domain controller logs to my sql database server. Things are going smooth and i m able to parse system, application and security logs successfully without any problem but when i want to parse logs of Directory services or DNS events it is giving an error stating that Dnsevent.evt is using by another process. I tried to stop some processes but tht didnt work. Pl. help
