Our network is configured to use RPC with Outlook. My particular setup works fine. I'm noticing that for some people though I'm having a problem getting them to authenticate. It just keeps asking for the password. I know I'm not providing much information, but assuming I'm setting up the clients the exact same way on each person's laptop, what could be going on locally that would screw up the setup? Is some cert missing, etc? No errors pop up, it just keeps on asking for the password.
