Administration requests managed by another domain

I manage 5 different servers in 5 different domains wich are supposed to have no administrative links except for routing and user databases replication.

I just found out that two administration requests from 2 different domains have been sent to a third one AND processed.

I saw that because of the “This request originated in the XYZ domain.” message.

I have checked the servers’directories : could not find out what’s wrong !

Any idea ?

Thanks.
