Well what I was trying to figure out was:
"Windows server this query returns 0 rows.
In Windows server same query using like
select * from firma1.desktop where baas like '_LOGIFAI'
returns properly 16 rows. "
My suspicion is that first case is for the replicated database and failed for the reasons you mentioned and that the second case is for a 'native' Windows instance. Just trying to get confirmation.
Nothing in the OP's text suggests a different server is involved - rather same server but LIKE vs equals.
The LIKE query probably doesn't use an index and thus finds the relevant data via sequential scan and equality checks on each record.
