Error when restoring 4.0 database with 5.01 client on SQL 2008

i got error message:

8009,“42000”,[Microsoft][ODBC SQL Server Driver][SQL Server] The incoming tabular data strean (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 89 (""): Datatype 0x00 is unknown.

Any help, please.

Hmmm …

Could you exactly describe how you proceeded? When did the error occur? Could you create a SQL Profiler Trace during the restore to see the statement which causes the problem?

Regards,
Jörg
