The following error is shown in System Log of Event Viewer on the target host:

The World Wide Web Publishing Service (WWW Service) did not register the URL prefix http://testsite.tld:80: for site 4791. The necessary network binding may already be in use. The site has been disabled. The data field contains the error number.


Same binding already exists on some other site in IIS.


  1. Open applicationHost.config file located in C:\Windows\System32\inetsrv\config (alternatively you can use the C:\Windows\System32\inetsrv\MetaBase.xml file)
  2. Search it for the record like or
  3. In the found section note the site name, it should be something like webspace_00100001 - domain (1234)
  4. If this site is needed, then cancel the failed task and create site with another name instead of testsite.tld. If site is not needed, remove it from IIS Manager (or remove conflicting binding from it) and restart the task. It should be completed successfully.
