OS All Windows 7
All Gigabit network wired going to a Netgear level 2 switch
Untangled, is my DHCP server and gateway.
My comptuer can't access my network any more, when I do a ipconfig /renew i get this message "An Error occurred while renewing interface Local Area Connection : The name spacified in the network control block <NCB> is in use on a remote adapter.
The NCB is the data"
At first this started on my desktop, I rebooted everything, untangled switch computer. and now it is doing the same thing on my laptop directly wired and a netbook wireless.
When the problem first started, I couldn't resolve my desktop name, I had to use my direct IP, (but I has internet and everything seamed to be working. so that is when I did a ipconfig /release and a ipconfig /renew, and then the real problem began.
I think it is an Untangle problem, because I plugged my desktop directly into my Untangle box, and got the same result.
I also got an old Linksys router I wasn't useing and both my laptop and desktop got DHCP served from that just fine.
Also, I don't think it is an windows problem because I notice that untangle didn't DHCP serve my desktop's PXE request.
Any help would be much appreciated.
