Ok, this is a complete no brainer...
SVCUTIL Error: "'svcutil' is not recognized as an internal or external command, operable program or batch file."
This means you don't have svcutil in your environment variable path. So to run this you would have to give the entire path of where svcutil lies. Which would be "C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\svcutil.exe". Alternatively, you need to concatenate the directory in which svcutil.exe lies in your Operating Environment Variable Path.
In Windows Vista, Open Windows Explorer (Windows + E), right click on "Computer" and go to "properties". Under "Computer Name, Domain and Workgroup Settings", click on "Change Settings", you will get a security warning, click "Continue".
You will see the System Properties Dialog. Go to "Advanced" Tab and click "Environment Variables" button at the bottom. Look for "Path" under "System Variables" list and click "Edit". at the end of the Variable Value, Concatenate ";C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\;". The ';' is the separator for variables.
Now open command prompt and type in svcutil and click enter. You would be able to see svcutil run. you don't have to give the entire path any more.
