I am trying to use VS2010\'s 1-Click Publish feature to deploy a test site from my laptop to my server. I have the firewall turned off on both machines and the MS Deployment
Restart visual studio.
I've had this one come up on a few occasions after having just successfully deployed a WebApp on a server running IIS 7.5. Obviously since a deployment/publishing was done successfully on the server just before this error came up, there was very little that could have gone wrong on the server setup/configuration (unless the previous successful deployment did something horribly wrong and removed some configuration parameters on the server).
After having rebooted the server, checked that Web Management service and Web Deployment service were running correctly, and verified from cUrl tool that a GET of the MsDeploy.axd was successful there was only one thing left to do. Restart Visual Studio. Magically post restart of VS publish started working again. All on its own. Magical stuff, this Web Deployment :)
