Nice to see we are helping Barracuda customers :-).

Just to confirm the two common errors with the netsh commands on Windows 2008 server:

C:\>netsh interface ipv4 set interface “net” weakhostreceive=enabled
The filename, directory name, or volume label syntax is incorrect.

i.e. the label doesnt exist/ misspelt / wrong case.

C:\>netsh interface ipv4 set interface 1 weakhostreceive=enabled
The requested operation requires elevation.

i.e. not enough permissions of user to run (needs to be admin)

Thank you for the tip. I searched all over trying to get 2008 working with my Barracuda. This did the trick in seconds.
