Funny thing that, linksys, AKA Cisco, has a FAQ specing setting the LAN speed and duplex to manual to resolve this said issue. Imagine that, network problems with a "cheap" switch... I should have got the Dell switch instead. Though not sure if it would have been much better.. Anyways, tis Christmas eve and I should be asleep... Else Santa will not come. You all still believe in Santa right... Peace to all, and a happy holidays. Mark ----- Original Message ----- From: Ruba Al Omari, Eng.

Do you have a multilink between the main servers and the clients? if the servers are communicating but the clients are not sensing the servers then it could be the multilink between the main boxes if any. If you can isolate the problem in a specific box, connection, segment, then you can troubleshoot it from there, please feel free to email me off list with the network configuration if you wish too. thanks r.
