Only Some Computers Lose Internet Access
Posted on 2011-09-28
I've got an Active Directory network with about 50 computers. We started having issues last week and it came back today. Only some of the computers are losing Internet access. I've rebooted all the hardware I can. But I've got two computers I'm working on...one is online and the other one isn't. However, all the local network connectivity seems to be fine on all the computers. The computer that can't get online can still get to mapped network drives. But the Internet access is sporadic...sometimes works, sometimes doesn't.
It may be something related to different network switches, but I haven't confirmed that yet. (Although I rebooted all of them).
It also seems to be affecting something funny with some of our internal websites. Again, not confirmed...but could it be something with DNS?
It's all really weird and inconsistent...the worst kind of problems. Any ideas?
