NetworkAdapterConfiguration (with python & WMI)

Simple Python script for changing several NetworkAdapterConfigurations
on a W2K-Client (such as DefaultIPGateway, Dynamic DHCP, automatic 
DNS-Serveraddress, DNSSuffixSearchOrder). It needs the python sw (see
winst scripts) previously installed.

# 1. Loesche DefaultIPGateway (geht aber nur bei               #
#    statischem DHCP, daher die erste Aktion)                  #
# 2. Enable DHCP fuer jedes Interface                          #
# 3. DISABLE LMHOSTS                                           #
# 4. DNS-Domain fuer jedes Interface                           #
# 5. NetbiosOption ="0" f.j. Interface (0=Netbios ueber DHCP)  #
# 6. Enable automatische DNS-Serveradresse                     #
# 7. Changing DNSDomainSuffixSearchOrder                       #
# 8. Ausgabe der Einstellungen (IPConfig-like)                 # 
# 9. OPTIONAL: Dynamische DNSRegistrierung                     #
