Roaming User Conversion: Adminp not finding DBs

hi

strange problem on 10% of the user we are converting to roaming user.

the roaming-databases are created correctly on the server, the admin is able to open these dbs.

but on the console i always get the following error message:

The replica of the database roaming\XXX\names.nsf has not been initialized by the replicator.

event the acls of the database seem to be correct (server is manager).

i tried to re-convert to roaming user with another roaming-directory on the server, same problem.
