Unable to open connection to host NWDS

Dear SAP gurus.

I have a issue when I trying to connect a DTR.

Originally the repository was in AS400 (host: pgsap), was upgraded to AIX (chdjmd).

After upgrading when I try to download the code I get the error "Unable to open connection to host".

The issue is that the NWDS tries to connect to host pgsap instead of connecting host chdjmd.

I need connect to host chdjmd no to pgsap.

I tried deleting the folders .dtc & .dtr but the NWDS still trying to connect to the wrong server.

Regards,

Victor Carmona.
