Error While Changing Custom Resolver

Hi all,

here is the context of our problem:
- Publisher : version SQL Server 2005 SP2, table in SQL Server 2000 (80) compatibility level, publication in SQL Server 2000 compatibility level
- Distributor : SQL Server 2005 SP2
- Subscriber : SQL Server 2000 SP4 + hotfixes (version 8.00.2187)

There is only one article in our publication (a simple table with a GUID and a nvarchar(50) columns), and we have left the default resolver.

1 - The first synchronization of the subscription is successfully completed, and it is the same for the different updates/inserts/deletes or conflicts.

2 - Then we change the Resolver of our article by our own COM-Based Custom Resolver (developped in C# 2.0). This resolver only change the default behaviour: the subscriber always win (this is for a test, in the future we will have a complex business logic). All the synchronizations works fine and do what we want in the conflicts.

3 - We rollback the resolver to the default one... and here is the problem!

The synchonizations stop to work correctly. For all of them we've got the same error:
quote:Replprov.dll , 2007/09/25 14:26:07.591, 4000, 16890, S1, ERROR: ErrNo = 0x80045017, ErrSrc = <null>, ErrType = 8, ErrStr = The schema script '

It is no more possible to synchronize this subscription... Any remark will be helpfull cause we did not find anything on the net concerning this error.

Thanks a lot!
