Recap on netsh (Windows)

Dump interface config (Tested on Windows 2003 STD SP2)


Save your perfect running config (real pain add many many ip's in windows manually).

C:\documents and settings\Administrator\My Documents>netsh -c interface dump > interface.server1.txt

Want to update or change some values? Just edit interface.server1.txt (carefull about correct syntax - http://technet.microsoft.com/en-us/library/cc738592(WS.10).aspx)
Save as new file like "interface.server1.new.txt"

Deploy your new settings

C:\documents and settings\Administrator\My Documents>netsh -f interface.server1.new.txt

Something went wrong or testing done?
- Revert to old config!

C:\documents and settings\Administrator\My Documents>netsh -f interface.server1.txt


Violá! Be sure always verify settings and connectivity!
