Can login as Admin, but not as user

3 month old Dell OptiPlex 3010 desktop that is exactly the same as 10 others in our office.

Yesterday, our LAN went down due to AT&ampT DSL problems. When it connectivity came back, we were unable to sign into this particular PC. We continually got the &quotPC offline....Use last known password&quot error. The last known password never worked.

Although, we could log in via the Admin account without problem and it had full internet connectivity. Also, within the admin account, I could sign into that user account via the web/Office 365 Live using the password without any problems.

I reset the user password to Microsoft supplied temporary password via the Admin account, but this did not resolve the problem. I deleted the account, restarted the PC, the re-added the user account using the same email address, but still cannot login.

I now get &quotYou can't sign in to your PC right now. Go to account.live.com to fix the problem, or try the last password you used on this PC&quot.

Now, that may be a hint as to what the problem is. The user account is shiiping-at-our-company-dotcom (can't post links until account verified)but there was a secondary email account used in Outlook 2010 that was ourcompany-at-live-dot-com. Is it possible

that somehow it is mixing the two?

This a major problem because this PC runs the shipping department and needs to logon from that email address

Any suggestions greatly appreciated
