Please use EPDM Connectivity test tool in S-069274 to test again
If you have Windows Firewall running on the client machines that can possibly block EPDM from using ports 1433 and 3030 on the client machines.
If you have telnet installed on a client you can open a command window (type cmd in the start search box).With the command window open put in "telnet MYSERVER 1433" or "telnet MYSERVER 3030". Telnet will then return an error message or a blank screen. If you get a blank screen that means you are able to connect to the server on the specified port and telnet is waiting for instructions to send. Just exit out of the command window to get out of it.
If you do not have telnet installed you can install it by opening a command window as administrator and then running this command "pkgmgr /iu:"TelnetClient".
That will take a couple minutes to run in the background so give it 5 minutes. After that try the telnet commands again.
If you are not able to telnet to the server on those ports you can go into the control panel --> Windows Firewall --> Advanced Settings (from the left column). In the firewall dialog click Outbound rules --> New Rule
Create a new rule with rule type "Port", "TCP", Specific ports: 3030, 1433, "Allow the connection", any of the three profiles: at least top two and give it a name.
After that try telnet again.
If you don't have Windows Firewall running on the client is there a network firewall?
You could also try using the servers fully qualified name: MYSERVER.Domain.com or the IP address.
You could also try specifying the server in the hosts file on the client: C:\Windows\System32\drivers\etc then edit the hosts file. Add a line at the bottom like 126.96.36.1996 MYSERVER.Domain.com
Okay, to the SQL server was using a dynamic port so I changed it to a static port 1433. After that, "telnet MYSERVER 1433" is giving me a blank screen, which I think the connection is working.
However, the same problem still remains saying cannot access the items in the database...
It appears you have established the communication is up and running, and SQL server exists.
Are client and server versions the same? For example, a 2014 SP5 client cannot connect to Server 2014 SP2, it has to having matching SP's. (The error message is the same, but im not sure about the log entry.)
If you log to the vault in the Administration tool, does it present you with the same error message?
Is IPv6 active? try deactivating it.
I guess EPDM 2014 won't work with Win Server 2016?
