We are trying to publish our vSphere Web Client via ISA 2006 to the internet. The web page makes it past the "Loading" screen and starts to display the logon fields. We then see this error:
If you click OK, the logon fields are displayed, but the server field is blank. The web client is working perfectly on our internal network. Has anyone seen this particular error message and gotten around it? Are there any other ports other than HTTP/HTTPS that need to be opened on ISA?
