RE: [NTISP] 100Mbit slowdown problem

We have tried to set the server to 100FD but it would only run for a short
period of time before going back to 100HD. The same thing happens on the
workstations with 100FD settings.
We are running a 16 port Planet 10/100 Switch.
Both the server and CAD stations have 3Com 10/100 3c509's, I believe that we
have ruled out cabling and the cards in the PC seem ok it only the switch
could be the problem.
I will be contacting the supplier today.
Thank you all for the suggestions
Regards

manually set the switch port and the card to 100 mbit full or half duplex.
When these settings don't jive between the card and switch it can cause the
problems you describe.
