Strange security and general errors

<p><span style="color: #000000;">Enterprise build 3471, service pack 2, client stack access via virtual Citrix servers.</span></p><p></p><p><span style="color: #000000;">I'm starting to see odd combinations of errors in the message center.</span></p><p><span style="color: #000000;">Users who find all data missing for all sample sets previously viewable in any project get the general error:</span></p><p><span style="color: #000000; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"><em>     Chrom open for read failed, file <a href=""><span style="color: #000000;">\</span></a>... err = 'Logon failure: unknown user name or bad password.'</em></span></p><p><span style="color: #000000; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">as well as a config. manager/security error:</span></p><p><span style="color: #000000; font-family: 'Arial','sans-serif'; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"><em>     Unsuccessful attempt to confirm identity with user account 'John_Doe'.  See System Audit Trail for details.</em></span></p><p></p><p><span style="color: black; font-family: 'Arial','sans-serif'; font-size: 8pt; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"><span style="color: #000000;">Anyone have any idea what's up? There are no login failures associated with these errors (timewise). This has happened to 3 different users in the past couple of days. My suspicion is that they changed their Empower and/or LAN passwords and it is just taking a little while for one of the servers to get up to speed on this.</span></span></p><p></p>
