Strange Network problem - Router related
I've got the weirdest problem ever...
On a network, I swapped the router from a standard home Netgear (Was just a stop-gap solution for a rushed building move) to a Draytek Vigor 2830, everything seemed to be fine. I booted up a few computers on the network and the majority of them work. The only problem is with the 64-bit machines. Every single machine running a 64bit OS crashes on the login screen. They'll boot into safe-mode with networking and work fine, the minute they're booted normally on the network with the Draytek they just lock up. After long and fruitless conversations with Draytek and millions of different firmware versions, I'm nowhere. I've tried Google with no luck... It's like it's never happened to anyone before.
I can get round it for now by re-imaging with 32bit and then they work fine but it's hardly a great solution. The 64-bit machines were actually ordered by mistake a while back, never thought it would cause this sort of problem!
Does anyone have any ideas at all? It's driving me mad!
