nav 3.10 sql user login error

Hi all, we’ve just completed a migration from 3.10 cside to 3.10 SQL. A few users (only win2000 so far) have the following error message when logging in: “The current ANSI or OEM code page on your computer does not match the 437 code page of the SQL_Latin1_General_CP437_BIN collation for the sqlattain database. You must ensure that either the ANSI or OEM code page matches the database code page” I’ve checked regional settings/code page settings to be the same with users that work / server. Any ideas anyone ? Thanks
