Computers can't connect to the mirgae Server

Hi,

I've the following issue.

We've setup an Mirage 4.0 Server and installed the Mirage-Agent at 10 clients.

Eight of them are working fine. The other two can't connect to the server. I figured out the they don't have an UUID in the BIOS.

The Mirage-Server log shows up in the eventlog, that the uuid=ffffffff-ffff-ffff-ffff-ffffffffffff for both computers.

How can I make the Computers unique in mirage?

And how will mirage create the AgentID?

Thanks for your help?
