Windows Server, how do I get powerpath to see new paths?

I have some windows 2003 Servers that have powerpath 4.5 installed connecting to clariion 600 storage.

Some of these servers only were zoned down one path, but have 2 HBAs. So I added a second path but powerpath doesn't detect them. HBAnyware sees the new zone.

Does this require a reboot? What powerpath command should I run to see the new paths? There isn't a windows version of powermt config is there?

I can see the new zones are setup correctly, and the initiators show logged in and registered in connectivity status of Navisphere.

What else needs to be done to force windows servers to pickup the new paths?

Thanks,
Taylor
