Problem
We keep getting this warning on one of our Notification Servers:

Date: May 31 23:53:51:002
Source:
Altiris.NS.UI.AltirisWebApplication.Application_PreRequestHandlerExecute
Description: provided fallback culture(en-US) for non supported languages.
Culture name en-securid is not supported.
Parameter name: name

Environment
Notification Server 6.0 SP2 Hotfixes 19, 20, 22
This has also been observed with Notification Server 6.0 SP3 R2.

Cause
It is either an encrypted browser or the language is not a supported language so the Altiris Console defaults to English US language for the browser.

In one case, a user of the Altiris Notification Server Console 6.0 was using Internet Explorer* 6 MSN toolbar, which we believe received a Microsoft* security update or upon installation of the Cisco* VPN software added a "User-Defined" [en-securid] to its languages.

Resolution
This is normal warning message when the Altiris Console cannot determine the local Language settings of the Internet Explorer browser or when it is an encrypted browser. Try changing the language settings of the browser and possibly "User-Defined" [en-securid] in Internet Explorer > Tools > Languages to correct this warning.
