My email lost it's connection suddenly and prompted for user login.  Given correct credentials it still would not log in.  The event log on the computer shows that my user experienced a account lockout.  Minutes later the account was fine.  

We have several administrators in the system.  I was wondering what exchange operations would lock out one account and not others.  

Windows Server 2003 R2, Excahnge 2007

Thanks.

I have never seen an exchange operation locks down an account. It is likely that some machine in you environment might has a malware which discovered some accounts and is trying to guess their passwords.

Please check in DCs for Security Logs and see if your accounts is trying to authenticate using wrong credentials or put a sniffer in your networks filtering for destination your DCs and then creates a search for your account.

That person could have a managed password for the mail client.

On an XP machine:

Ctrl pannel>>users>>advanced>>managed paswords

Delete any managed passwords saved on the computer for the mail client software to authenticate with.

The machine started having other problems including machine certificate problems with blocked all efforts to troubleshoot this problem.  It has been formatted and the problem has not re-appeared.  Thanks for the valid solutions.
