Hi Dimitri,
Firebirds server is installed on server and i can connect through OBDC from all workstations. The problem is only with the linked table on microsoft access DB.

I create a Db access 2007 and i put it in a shared folder. All PCs have a mapped network drive (Z) to access this database.
 
If i link tables from a pc "1", i can't read data from pc "2".

But if i open the shared DB from pc "2", delete linked table and i re-link tables from pc "2", i can read data from pc "2" but i  can't read data from pc "1".

The error is the same: "connection failed"


Do you need more information?
Thank you in advance
Adriano
