I'm not sure what's going on here, so any help or suggestions would be greatly appreciated.
Reasonable size network (50 PCs and 120 laptops, 2 DCs with DNS, DHCP) and every now and then the laptops won't log on to the network because it says it can't find the domain controller. By logging on to the local machine you can then just re attach to the domain and it's happy.
The DNS thats being given out is for the local server and also 2 of the LA one's as second and third. It was set-up this way by the LA approved supplier, should it have been?
Any ideas why it's doing this?
