spiceworks vs lansweeper

hey all

i'm considering helping out a nonprofit 30-student school near me. they're having networking issues.

the most concerning issue is they're "getting kicked out" of the network a few times per day. i'm not sure if they're getting kicked offline, or if they're just getting kicked out of the domain (or both).

to complicate things more, i'm a windows guy. they're all using mac mini's. not sure what their server is yet.

i'm leaning towards spiceworks, lansweepers site says nothing that seems to suggest that its good for checking network health / finding issues.

thanks in advance
