Hi Rick, you mean it is not possible to give different permissions to each company employees, or you mean I cannot hint public folder? I didn't deploy Windows SharePoint Services. I know only that WSS bases on ISS. Where will WSS save customer data: in SQL or in any folder on the machine? Must I create for each customer IIS Web Site? We have front-End and back-end Exchange infrastructure. Does WSS work in this infrastruckture without problem? Can you give me good information link about WSS deploying? Thanks. Best Regards Mustafa
