Deploying Web Parts In A Server Farm After Installing WSS SP1

After the installation of WSS SP1, deploying web parts in a server farm scenario with stsadm.exe may no longer be possible. Command line operations for "addwppack" may fail, producing a "server instance not found error". According to this post, the issue results from a failure to upgrade the IIS server during installation of the service pack. While the primary front end server may work fine, other servers in the farm may require the "stsadm.exe -o upgrade" operation. After upgrading full functionality should be restored. Try this solution if you are encountering similar errors.
