I've got 2 computers, Dell Latitude D800's on a network. Outlook will pop-up the Enter Network Password Box with all the info already filled in- click OK and the send/receive continues. I've tried resetting the password, clicking the save password option, creating a new e-mail profile for the machines, and increasing the timeout time in Outlook - but nothing is working. There are 6 other identical machines on the network that are not having this problem. One machine is running Norton Internet Security and the other is running McAfee Internet Security Suite. All machines have the latest updates from MS - office and windows.
