I have just installed a 3com switch, out of the box.
Plugged into our network, where we have approximately 10 PCs connected to a few 2k3 servers.
I have not set up anything on the switch as of yet, it came out of the box and replaced our older 24 port 10/100mbps switch.
Since I have replaced it, we are getting issues login into the domain.
I am getting errors in my event log saying that the domain controller cannot be found, yet if I plug the old switch back in, i don't get these errors.
I have implemented these in other clients offices and since we have had these problems I have checked a few client PCs at other offices and they are also getting the same errors using these switches.
Windows XP Pro pops up with a bubble after logging in, saying 'Could not reconnect network drives...' - As implied, we do not see this error message after putting everyone back into our old switch.
What could be the issue here?
Anyone seen something like this before? I have always seen this switch marketted as 'out of the box configuration should work for everyone.' so to speak.
