The problem affects all the machines on the networks; they all lose connection simultaneously. We're trying various things to try to resolve the problem. So far, at my customer's place, I have replaced one of the switches, turned off Norton Personal Firewall on one computer, replaced the RJ45 on one cable, replaced one modular jack, upgraded the firmware in the router (one of the bugs resolved is a router reboot caused by a multicast, maybe that'll help), and rearranged the cables between the other switch and the router so that all of the active cables were on the router and all the inactive cables on the switch, which I then turned off (so, instead of two switches and a router, there's now one switch and a router). Will find out tomorrow afternoon if these latest changes have had any effect. I meant to check to see if the router is plugged into the UPS, will have my customer check that tomorrow. -- Best regards, Scott mailto:Wizard@xxxxxxxx To unsubscribe from this list send an email to pcductape-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field OR by logging into the Web interface.
