Domino Admin

Dear Friends, I have two Domino servers in a cluster. Both on Domino 
6.2CF1. One on Win2K and one on Suse9.0. When I use the Domino Admin tool 
to list the servers in my domain, one of them has an icon that has a small 
yellow key over it (the Win2k one), the other doesn't(the Suse one). What 
does this small yellow key thing mean? Another question: When I view the 
Server Tasks for the Win2K machine, i can see the CPU Utilization as a 
percentange. But i cant see this on the Suse box. Any ideas why? 
Thanks for your help, Markus Bergh.
