I have an internal network running SBS 2008 (with exchange). I have a whole bunch of XP clients on this network and they are running perfectly, but the two Vista PCs I have are giving me some trouble.
When running outlook 2007, the users are prompted every few minutes to enter their password. The box says:
Connecting to sites
User name: Domain\User
When we put in the proper password, it acts like we entered it wrong. It will ask like 3 times before it disappears, and then it comes back in a few minutes. I know we are using the right password because it's the same password used when logging in, and it matches the Domain\User credentials being asked for. This is only happening on the two Vista PCs (newest service pack and updates already installed).
Now, I've done a fair amount of research on my own trying to find a solution, but most everyone is having a different problem than me. Their password are being accepted, but not being saved when they say "remember my password". And it comes up every time they try to send and receive something. My problem is that the passwords that should be working are being ignored or something. Outlook is actually running fine other than this. Even when we click cancel or enter in random passwords, we can still send and receive emails no problems (and we aren't prompted as a direct result of sending/receiving either).
This is very weird and I'm running out of ideas. One site suggested that I go to Tools -> Account Settings -> Repair. I tried this but it fails on "Search for user@domain server settings".
