Lenovo Laptop running Windows 8.1, all this was done as administrator
The user uses the laptop at several locations around the UK but yesterday he was unable to set the Ethernet LAN IP address, subnet mask, gateway or dns for the location he was at (a 10.1.*.* range). He could put the IPaddress settings into network settings (Start >> Control panel >> network and sharing centre >> change adapter settings >> local area connection >>properties >> TCP\IPv4 >> properties) and then OK-ed all the way back to the desktop, if he then did ipconfig in a dos box it came back listing a 169 address and was unable to ping anything on the local network (which is to be expected with a 169 address), if he went back to network settings the desired IP address was still there. If he set the IP address he wanted and then rebooted the laptop, the LAN connecting would be disabled upon reboot but the desired IP address would still be listed in network settings and IPconfig would give a 169 address. He did tick the validate setting box but that only told him there was an issue, not where the issue was or how to correct it.
If he set the IP address, subnet mask, gateway and dns to the setting to one of the other locations he goes to, the IP address etc. would be listed correctly in network settings and if he tried a ipconfig (in a dos box) it reported the IP address etc. he had set as you would expect although (obviously) he could not access the lan at that location he was at. At the end of the day it is only the third set of digits in the IP address and Gateway address that differs between each location the first, second and fourth all being the same (we did try changing the fourth set of digits on the IP address thinking of a possible IP clash but that made no difference). He had used the laptop the day before at a different location on the LAN without a problem.
Any thoughts before I wipe Windows 8.1 off the disk and revert to Windows 7?? (wiping the OS as I believe it is a OS based issue and reverting to Win 7 as he dislikes Win 8.1)
