Problem ze zmianą konf. IP z linii poleceń (dlugie)

Witam
Odnosnie tematu zmiany IP z lini polecen mam problem, pewnie dla was
banalny, ale bardzo prosze o pomoc. Chce zrobic skrypt zmieniajacy
konfiguracje IP w zaleznosci gdzie jestem (dom/praca - dhcp/static).

Po wydaniu polecenia w Win2k Pro: netsh interface ip show config

otrzymuję swoja domową konfigurację:

>Configuration for interface "{CF96ACBE-CEB1-4A05-92E7-054A6638A40B}"
> DHCP enabled: Yes
> InterfaceMetric: 1
> DNS servers configured through DHCP
> WINS servers configured through DHCP
>
>Configuration for interface "{AAF649FA-BA4C-4856-93CD-59B20D5402E2}"
> DHCP enabled: Yes
> InterfaceMetric: 1
> DNS servers configured through DHCP
> WINS servers configured through DHCP
>
>Configuration for interface "{E1554D30-3EFF-4419-924A-01F847564436}"
> DHCP enabled: Yes
> InterfaceMetric: 1
> DNS servers configured through DHCP
> WINS servers configured through DHCP

Wczesniej zapisalem konfiguracje do pliku "praca" poleceniem: netsh -c
interface dump > praca
Otrzymałem:

Jednak przy próbie załadowania konfiguracji poleceniem: netsh -f praca

Otrzymuję:
>Invalid interface {CF96ACBE-CEB1-4A05-92E7-054A6638A40B} specified.
