Do you have the Microsoft Telnet Client feature enabled on your station? Can you try opening a command prompt and running:
TELNET SOLARWINDS-LEM 9001
You should get something back like this:
HSQLDB JDBC Network Listener.
Use JDBC driver with Network Compatibility Version2
.1.0.0 and a JDBC URL like jdbc:hsqldb:hsql://hostname...
Connection to host lost.
Does that work?
