I've used the deployment tool 3.0 quite frequently of late to migrate our websites from IIS 6 servers to IIS 7.5. I'm getting a strange error now on my next server. When I run any msdeploy -sync operation I get a popup with the title "msdeploy.exe - EXCEPTION" and the text "Breakpoint A breakpoint has been reached." I can only click "OK." Even a "-verb:dump" command gives me this error. I can run "msdeploy /?" without error. I do see an error in the system log with an ID of 26, but that seems to be a fairly generic error.
When I try to run the sync command in reverse from the older webserver, I get an error telling me the remote service isn't running, but it is. I tried creating a package on the old server but I also get the breakpoint error when I try to import the package on the new server. I can't seem to find any information on this by searching the web.
Some further info: I've tried uninstalling and reinstalling but it doesn't help. I finally tried using Web Deploy 2.1 and it worked but I'd rather have the latest version.
