WinXP 64bit

I'm evaluating DC right now, my network consists mainly of Windows XP 64 bit workstations.

I'm wondering if DC supports 64bit, as I'm running into some issues and wondering if they might be related to this.

ie, patch manager sees the machines as having Windows Server 2003Professional Edition SP2, rather than XP Pro x64 SP2. I'm pretty sure this is related to why patch's I'm trying to install aren't executing.

also I have the port set as an exception in the firewall, the agent installed fine, but configurations that I'm trying to push to a test machine are all stuck at ready to execute.

I'm going through the admin guide documentation right now, but just want to double check this isn't just related to the machines being x64 bit and therefore unsupported.

Thanks
