Rebooting cleared your dns cache. running

ipconfig /flushdns

would have resolved the issue too. The PCs were remembering what the server used to have for an IP. They would have "forgotten" after a while as well. I forget what the default is.

Setting a static inside the DHCP scope won't hurt anything, either, so you're good there (the dhcp server... in this case your firewall... will ping an IP before assigning it, so it won't assign your webserver's IP to something else by mistake since it can ping it).

As for the IP changing if it's set to DHCP... maybe, depends what you set your lease to, and how often you shut your PC down, and for how long. If your dhcp lease is a couple of days, and you never shut your PC down for that long, it will always keep the same IP. If the lease time is just a couple hours, and you shut your PC down longer then that, you could change IPs.

Probably more info then you wanted on all of this, lol. Glad it's all working.
