Changing IP Address Feedback

I am looking for feedback from anyone who has gone through an IP address change. We are changing our IP address scheme to a private address. I am running NT40 and have the following applications and Services:

PDC – DHCP/Pri WINS
BDC – Sec WINS/SMS/SQL

All NT Servers have static addresses and Client’s use Dynamic.

How have client PC’s reacted to the new DHCP Scope? Have you had to physically touch each machine and release/renew? What about WINS? Should I just kill the database andlet it rebuild?

I’m not expecting any problems. I would just like a “heads up” from anyone who’s been through it

Thanks
