Outlook constantly asking for password

[Prophet]

I've just installed two new servers and attached the 20 users to the new domain. Everything has gone well apart from one PC running windows 7 and Office 2007. It constantly ask for the users password when outlook is open.

The server is SBS 2008 running Exchange 2007.

I've tried a couple of the registry hacks on the PC and removed/added the PC to the domain.

Any ideas?

I've had this problem many times with the exact software you are running

you need to service pack exchange 2007 to SP2

but, as it's SBS, you need to use a special installer, download both, and run the installer, then point it to the SP2 installer
