Strange Network disconnection problem - Dell Optiplex 360
Gets in to school this morning with a report that PCs in Science cannot login to network.
After much investigation the problem appears to be affecting about 40 computers.
Verified that switches/power etc. are all ok and we have plugged in our laptop which gets network connection and can login to the domain on various network ports.
The affected Dell 360 PCs are all reporting their (on-board) network connection as being disabled. Have tried to re-enable the network connection, but that fails and gives error.
Have tried uninstalling network hardware in Device Manager, updating drivers, resetting BIOS and various other troubleshooting things, but no joy.
I suspect we have had some sort of 'power spike' which has destroyed the network circuits on the affected PCs.....but I am not 100% sure!!
Has anyone had any similar problems to this?
If so, any advice or information greatly appreciated. I am at the point now where I think we may have to go out and buy 40+ small form factor network cards in order to fix this :(
