Dear Michael,<br><br>I hope your problem won't be a regular issue and you don't see it again. <br><br>All of the servers I've installed have a few tools by default to make tests in this cases (tcpdump (wireshark if gui), iptraf, iptables/pf,netcat,sysinternals(windows),...) and have a monitoring packages (Nagios/Ntop) in other machine to obtain data. And one monitor port in our switches to plug my laptop and sniff all traffic on each vlan. I saw a lot of strange issues but if networks and systems have not tools, you only can reboot and try to obtain an answer from logs.<br>

Dear Juan Carlos,<br>
<div class="im"><br>

<br>
</div>I couldn't make any further tests on that machine because I couldn't<br>
install any software on that machine because of the failing network.<br>
However, I took the opportunity and rebooted the machine last night.<br>
Guess what, everything is up and running again.<br>
Thanks for your assistance and sorry to the list for the disappeared<br>
problem.<br>
Reboot was no option through the week as this is a production machine<br>
under heavy load.<br>
