Note that the above code will only work under Python 2.5, since that's when
the "with" statement was added.
(Some of us are still stuck in 2.4 land :) )
In 2.4 and earlier, it could look something more like:
<code - untested>
import wmi
servers = open ("c:/servernames.txt").read ().splitlines ()
for server in servers:
wmi_connection = wmi.WMI (server)
f = open ("%s-services.log" % server, "w")
for service in wmi_connection.Win32_Service ():
f.write ("%s\t%s\n" % (service.Caption, service.State))
f.close()
</code>
