I have recently started using an app that sends NEt send commands via machine name or domain name across a network.
I have started to think that the switch that the network is plughged into (a straight forward class C) is somehow blocking the net send commands
ther eis no configuration on the switch as it was just plugged in as a dumb switch while the resty of the systems were sorted but never got round to configuring it
would there be any reason a switch would block broadcast or certain rewuests without a config in it?
im pretty sure its not windows this time as we have tried the machines on the same domain ina different switch and it works - although it is possible these other switches have DNS entries setup as it was another companies switch -
any suggestions as to where to start looking?
