Newly added IP addresses not selectable for IIS bindings

iis-6iis-7windows-server-2008

A colleague of mine added several IP addresses to a server, but these IPs are not appearing in the list to use with bindings.

This goes for IIS7 web sites and IIS6 FTP sites.

We found this KB article, but I don't have the offending patch installed: http://support.microsoft.com/kb/2551090/en-us

I don't think the server was restarted after the IPs were added as it is a live production server, but I believe IIS (at least from IIS6) was restarted.

What must we do to be able to use these IPs? They are pingable.

UPDATE 1:
I am able to RDP to the new IP addresses without issues.

UPDATE 2:
I was able to make them appear by adding them to the hosts file, but I'd still like to know what the issue is?

Let's come back to old time though this is old post. I recently came a cross this issue and I open services.msc, and then restart IP Helper, and all IP newly added comes up.
