did you check using netstat?
Linux / Unix / or Windows command window:
At the command prompt, type netstat -a
c:\>netstat -a -n
myserver# netstat -a -n
You should see a tcp entry for 1099
Thanks. with netstat port 1099 does indeed show up, whereas it didn't with nmap.
Unfortunately, I still keep getting the same Exception.
Does anybody know in which direction to look next?
