Hi !
I’m currently dealing with some problems between ADNM server and MS SQL Server 2000, I keep getting database related errors like those (my eventlog is full of it :-):
23/07/2007 09:27:51 1185175671 SYSTEM 1644 Database command failed [CClient::OnPop, 80004005]: Échec de la connexion

The MS SQL Server is working fine, even when the error occur, and the only solution I find is to fix this is to restart the “avast! Management Server” service. After a restart everything get back to normal.
I think that the problem mights occur after MS SQL Server database’s backups.
Hoping you got a solution for me 
Thanks.
