PVA Agent installation fails with the following error:
This error states that "
preInstall.vbs" script is unable to connect to IIS in order to configure Offline Management service websites. Basically it means that IIS engine is not processing requests correctly.
To successfully install PVA Agent it is necessary to have fully functional IIS on the Hardware Node.
Root cause of the IIS failure can be determined by checking "
System" and "
Application" logs in Event Viewer. If the logs do not reveal any useful information and all attempts to fix IIS on your own fail, it is recommended to contact Microsoft support to get qualified assistance.
