Thank you @sharon4pal . Should I understand you and @sharafadeen work together in the same company/project?   In this case, my recommendation stands.   1- you can give a try to update hostname and ip with the SDM tool named Update Hostnames 2- Afterwards, check in the metadata and mainly in the files (libnames in SAS code/autoexecs, configuration files, etc) 3- Check firewall and DNS configurations (in server and in the network), and permissions set in databases. For the firewall, check always first with ping and telnet (or similar tools). 4- Align with SAS Technical Support if still does not work completely, as it might some additional updates in WIP database, but it would be better to do it with Tech Support.   Of course, after every iteration, validate as much as you can. Motto here is "test, test, test".   You can temporary workaround the DNS resolution, by adding a line in /etc/hosts (UNIX) or C:\Windows\System32\drivers\etc\hosts (Windows), but this can help only with hostname (short and FQDN) and DNS aliases. If the communication has defined the IP instead, this won't work.   Best regards, Juan   ... View more
