Microsoft SBS 2003 Connectivity Issues

November 17, 2008

Two months ago, Onsite Computer Services in New Orleans was called to troubleshoot intermittent network connectivity problems with a Microsoft SBS 2003 SP2Onsite’s predecessor installed the SBS in January of 2008 and since that initial installation, the server seemed to periodically drop its network connection.  As the situation decayed over time and lost connections became more frequent, the client’s accounting system realized increased data corruption from the intermittent connectivity flaw.

Our predecessor seemed to follow proper protocol in attempting to troubleshoot the problem.  The tech claimed he replaced the switch, the server Ethernet cable, the existing Broadcom NIC with an Intel NIC, the Intel driver, and disabled the TCP Chimney, all to no avail.  The system worked as designed for a few days but the SBS would eventually drop its network connection.  Totally frustrated, the tech finally relented and the business owner called Onsite Computer Services in New Orleans.

In an effort to isolate the problem, Onsite Computer Services retraced our predecessor’s efforts.  Troubleshooting is supposed to be an exact science and sometimes a small detail provides direction.  All of the Ethernet whips from the punch down block to the router were machine-terminated, while the Ethernet whip connecting the router to the server was terminated by hand.

Onsite replaced the Ethernet cable for the server with a machine-terminated cable and thus far the connectivity issues have ceased.  Upon closer examination of our predecessor’s hand-terminated Ethernet cable, Onsite noticed the RJ-45 connectors on the whip were different – one smoked and the other clear.  Using an eye loupe to closely examine the connectors revealed the clear connector was designed for braided Ethernet cable, while the smoked connector was designed for solid Ethernet cable.  The braided Ethernet connector apparently failed when used to terminate solid Ethernet cable.  The devil IS in the details!
