database's collation???
what is that?
how can i check that?

that it is:
easiest way to check it: in enterprise manager, database properties.
how to specify the default collation for an sql server instance:
However, if you installed all by default options, you shouldn't have this problem.
Did you try setting up a new database on the same SQL server instance and installing the membership in that database?

d*** the collation is different!

what are the risk to change the collation?

hi create a new database on the server where i have an error
i set the collation on French_CL_AS (the same collation on the working database)

i always have that error :
Setup failed.

An error occurred during the execution of the SQL file 'InstallRoles.sql'. The SQL error number is 446 and the SqlException message is: Cannot resolve collation conflict for equal to operation.
Cannot resolve collation conflict for equal to operation.

i don't where to look now... regards
the error is probably due to a join between 2 tables with different collation. This is either because the created membership tables have the default database collation and they are joined with some system databases (master maybe) or because (and more likely) the tables are created by aspnet_regsql with a different collation than the other tables in your database which have the default database collation. In this case, I don't think you can make aspnet_regsql create a different collation, but you might change the tables manually.
