upgrade wsconfig from command line problem

I have 2 running sites (plus cfadmin) on an IIS 7.5 server.  I want to run the command line to use wsconfig to update the connector on the smaller production site before trying it on the larger one or all.

If I run this command to get a list:

wsconfig.exe -list

There are 5 configured sites and 2 unconfigured sites

Configured Site Number and Site Name:

  0              All

  1              Default Web Site (All)

  2              cfadmin (All)

  3              site1 (All)

  5              site2(All)

Unconfigured Site Number and Site Name:

  4              ftp.site1

  6              ftp.site2

Per the docs, to upgrade site1 it would be:

wsconfig.exe -ws iis -upgrade -site "site1"   it returns

The Internet Information Server (IIS) connector in site1 can not be upgraded due to the following error:

This web server has not been configured for ColdFusion.

Huh?  List shows it's configured (and CF does indeed run fine on it), but upgrade tells me it's not configured.

I did also try

wsconfig.exe -ws iis -upgrade -site 3 and got the same error.
