After implementing MICROSOFT CRM 3.0, I decided that it would be simpler to just mainly use the web client instead of through outlook since at our company we have a mixture of XP home, and windows 2000 professional workstations. When accessing the website from IIS via , on the XP workstations a prompt connect to domain as comes up. But on the windows 2000 professional workstations, it automatically logins via the local login. Is there any way to work around this or to force prompt on the windows 2000 workstations for the domain?
