We have been having alot of issues at one of our locations. I discovered that we have two computers with the same name? what kind of issues would this create?
Quite a few. I'm surprised it even let you do that to be honest.... I would imagine renaming the machine and restarting whichever PC is the master browser will go a long way to fixing your problems.
This depends on how the network is configured if you are using DNS then yes there is going to be problems if not then traffic is routed via IP address though again it can depend on the application.
JamesMcS suggestion should at least help diagnose the problem (though not sure what you meant (literally) by master browser )
