Can not set specific IP address including DNS and gateway

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)

If the laptop is a company laptop and registered for domain use, the user should not be allowed to make any changes on the unit, without authorization by the IT department.

Now that is out of the way. The User should not have to set any IP settings to connect to a network. If they are getting a 169 IP, that means the router/gateway does not either allow computers attached to it without IT/LAN coordinator permission, the person that set the router/gateway up, only allows authorized computers on it, and is using MAC security, or the user is trying to connect to a locked down router that uses only Static IP's.

The OS has nothing to do with this. There is no need to install Windows 7 on the unit.

It is on a doamin and the user does have the authority to change the IP settings to a pre determine set of addresses for each location..

The IP address is not controlled in anyway by the gateway or the router (in this case the same unit) and there is no mac address control.

It is not a case of the network is rejecting the change of IP address (to this one specific address), the laptop refuse's to change to this specific address (which it has done quite often in the past) but will quite happily change to any other address that is entered into the laptop.

If the user is trying to connect to a domain, he needs to get in touch with the IT/LAN coordinator to add his laptop to the domain. The IP is going to be handled by either the router or the AD DNS server.

There should never be a need for the end user to have to set Static IP settings to get on a network.
