I have a Vista Business user who, several times a day, gets a dialog box on her screen asking her to re-input her network password. When I have looked into her event logs, she has multiple entries for event 4634 (logoff) and 4624 (logon), which may or not be related.
I got her to reset her network password and restart her PC, which appeared to solve the problem for a day or so, but it's now happening again.
The system she's working with is a Windows Server 2003 SBS - the only server in the company. In the Security event log on the server, there are multiple instances of event 538 (User Logoff) and 540 (User Logon) for her user ID.
Thanks in advance
