Hey all, I have an interesting drive mapping issue. Drives map fine, but when you click around too much, the computer chokes and you get the error "the local device name is already in use." I've played with GPO file permissions as well. It's got to be something DNS related, however I have no clue what it is. The windows server is running out of the box DNS, set up appropriately, and a router is providing DHCP. DHCP is only use for computers that are considered "guests" by the wireless system. I've tried editing the DNS entries in the machine to only point to the server, and reinstalling the NIC drivers on the server (They're Broadcom NetXtreme II GigE NDIS drivers if it's relevant). There are NO A records on the server pointing to the clients using static IP. Something else - ipconfig /flushdns ipconfig /registerdns fixes the issue sometimes, until it does it again. To boot, the internet is excruciatingly slow for whatever reason. The server is set to a static address as well. Any ideas? I can't find anything like this anywhere.
