Problems with Microsoft FTP

Hi,

The flow service does not seem to work well with IIS Ftp servers, where as it works just fine with a Unix based.

I changed the Unix Support Setting in the IIS and it works fine.

The problem here is my customer is not ready to change any settings on the Production Box. I was wondering if there are any Microsoft FTP supported services i can get or a possible solution.

Does anyone know hot to set this setting on IIS? or even better still, make the webm services work flawlessly with microsoft ftp?
