When Server Ping reports an unsuccessful connection, check to make sure that:
Adaptive Server is running on the target server.
A network hardware connection exists between your client machine and the target server.
The server meets the minimum hardware and software requirements (see the Adaptive Server Enterprise Installation Guide for Windows NT).
The network software is installed and configured on the client and the server.
The connection information in the sql.ini file is correct for the server.
The connection information in your client’s network configuration file is correct. For more information, see the Net-Library documentation for your client.
The format of the connection information is correct for the network protocol. See“Components in the sql.ini file”.
If you need to edit sql.ini, use dsedit.
WARNING! Make sure that no more than one copy of any Net-Library DLL is installed on your computer.
