MS SQL-6.5 local names of month/days differenet in NT and Win95/98

Dear colleagues,
I have a problem with MS-SQL Server 6.5 Service pack 5.

In ISQL_W if executing SELECT GETDATE() i have a result 5 mai 1999
19:54 from  PC with NT-Workstation 4 with
regional setting Norwegian (Bokmal) and default language for SQL-login

If i execute the same script from the same SQL-Database & same SQL-Login
from PC with Windows-95/98 and same regional
settings i have this result: 5 may 1999 19:54

The problem is in names of months & days. Because of this a program that
seems to be working quite nicely under NT
workstation 4.0 is not working under Windows 95 or Windows 98.
Can you please help us to resolve this problem.

Best regards
Ivo Gentchev
