1. Download the Log Parser tool from Microsoft here. I know, it’s old but works great.

2. Dump your IIS log files somewhere (ie: c:\temp\logs).

3. Run this in cmd:

C:\Program Files (x86)\Log Parser 2.2>logparser “SELECT * INTO iisLogs FROM c:\temp\logs\*.log ” -i:iisw3c -o:SQL -server:localhost -database:webLogs -username:sa -password:yourpass -createTable: ON
if you’re on 32bit, run Log Parser will be in this folder:

C:\Program Files\Log Parser 2.2>logparser “SELECT * INTO iisLogs FROM c:\temp\logs\*.log ” -i:iisw3c -o:SQL -server:localhost -database:webLogs -username:sa -password:yourpass -createTable: ON
