<p class="MsoNormal">Thanks Bob and Chad – those are good suggestions for troubleshooting. I also received a private response suggesting that it’s a problem to NAT the Sierra client through only one IP address, and that he had solved the problem by creating
a pool of IP addresses on the firewall for Sierra to use. That sounds like a likely solution, since the Sierra client opens a ton of connections when it starts (I think I’ve heard others say that the firewall can run out of ports for the outgoing traffic).<o:p></o:p></p>

<p class="MsoNormal">Hi Phil. For either situation, have you tried enabling logging in a user’s (your) iiirunner.lax file? I’m less optimistic about this helping with this morning’s problem, but you might get lucky anyway.<o:p></o:p></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Something on our local network (or some software on our PCs?) is giving us problems. Any idea where I should look?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We continue to have occasional problems with “JAR file not found” when starting the SDA (Sierra staff client) – this is apparently a problem on our network, possibly related to the large number of connections the SDA makes at startup to
check each of its 80 or so JAR files against the version on the server (this might look a little like a DDoS). But today something different happened.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We had a different problem this morning with SDA. Existing connections to the server continued to work (one person logged onto Sierra a few minutes before), and we could telnet to the port that this program uses and use the classic catalog
and Encore, but from about 9:00 to about 9:45 when we tried to start the SDA, it closed after a few seconds and gave no error message. This happened on at least four different workstations. I think that one workstation was able to connect during this time.
After about 9:45 I haven’t been able to get the problem to happen again.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any idea what might cause this? DNS was working. The person at III support didn’t see anything wrong. He advised me to delete the contents of the jarcache folder and then try loading SDA; it did not populate that folder at all, which is
the first thing that happens when SDA connects to the server.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m waiting for a call back from our firewall vendor to see if they can see anything on our firewall.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I checked the switches that the staff use and found that the DDOS protection feature is disabled.
