If you have a computer that is connected to a domain and is plugged into the domain network but doesn't have the domain profile active in the firewall settings of Windows 7 check to make sure you have your domain DNS server set as your primary DNS.
I had a client have an external DNS set for "faster internet" but it was causing errors on the machine because the PDC couldn't communicate with it correctly.
A client of mine was having the error 0x8004010F in Outlook 2010. I repaired the PST and it fixed 30 or so errors but I was still having the issue. I ended up creating a new Outlook profile using the following link...
After creating the new profile I could not open or export the previous PST. I realized she had checked the option Run this program in compatibility mode for: Windows XP checked. Once I unchecked that Outlook 2010 could open & export the previous PST.
If Outlook 2010 is prompting for UAC everytime you open it check to make sure you don't have Run this program in compatibility mode for: or Run this program as an administrator checked.

"You receive various Stop error messages in Windows 7 or in Windows Server 2008 R2 when you try to resume a computer that has a large SATA hard disk"
