Changing IP Address Feedback

I did this for a company and it was pretty seemless. As far as the WINS database they opted to start from scratch and that worked out pretty well for them.

You'll need to delete all the entries on WINS. We deleted and re-entered all the NT machines on Server Manager. In some Win95 machines, we had to delete the *.pwl for some unkwon reason, but after that it worked fine.

Good luck!

I did this for some big and some small companies. If the clients and the servers are on the same network cabling you should not get into trouble. But don't you have printers on the network with a static ip address? For the wins database, just kill it it is not useful to transport to the new numbers. Let it rebuild by clients loging on to the network with a new dhcp scope.
If you are using SMS you can get some odd errors on the sms database, because sms sees computers with names on other numbers, if the clients are NT, you can get a strange error telling that it can't load sms client, the solution is to reboot once again and the problem will be solved.

Other equipment what could have a ip number are switches, routers some hubs. Look toall the hardware attached to the network.

Good luck and get the job done. ;-)

I would do it over the weekend, but is should pretty smooth

Reconfigure DHCP, Wins (new database)
Just change your printers, routers, ...everything has an static IP address

SMS will complain a bit but, if your PCs are rebooted a few times it will aknowledge the changes

You could run a sript to make ipconfig /release and /renew on the clients

Good luck

Basically to make it as seamless as possible, you need to release all addresses on clients first. My way: do this over a weekend and have your users (if they're up to it) or you/your staff go to each WS before shutting down for the weekend and release the IP addresses, then shut down. Then change your server IPs first, then your other static IPs, then set your new DHCP scope (don't forget to disable the old one!), kill the WINS database (just delete it and let it rebuild), then when your clients are turned back on they will get a new IP address and re-register w/WINS. No sweat!
