I have a laptop (Sony Vaio Z running Windows 7) which won't connect to my work network. It was fine until a couple of weeks ago when we had a major network issue. The network and domain were rebuilt virtually from scratch, and every other machine migrated across fine.
This laptop, however, just won't. When starting the machine the wireless spinning circle icon appears for a while, then reverts to the "not connected" icon. Normally I'd go and clear out all the network settings and start again, but I'm unable to open either Manage Wireless Networks or Manage Devices to do so: both just hang indefinitely.
Is there any manual way to remove everything Windows knows about networks, and let it work it out itself, or am I looking at a full format? (Less than ideal, this is the bosses machine and I'd be interrupting him for too long at a busy time)
