Citrix PS 4.5 Error"...configured XML Services...failed to respond..."

Citrix PS 4.5 Error"...configured XML Services...failed to respond..."

Citrix PS 4.5 Error"...configured XML Services...failed to respond..."

I am running Citrix Presentation Server 4.5 on a Windows 2003 machine. I am also running the Web Interface on this machine. When installing the web interface I received an error regarding Port 80 already being in use by the XML Service. I then followed the directions from CTX107683, which Configures the XML Service to Share with IIS. After XML was sharing with IIS I was then able to successfully complete the Web Interface install, but here’s the issue… I am able to go onto the web page I just created but after I log in with my correct credentials, I am receiving an Error:
 “The supplied credentials could not be validated. Either they are incorrect, or there is a problem with the authentication system. Try again, or contact your help desk or system administrator for help.
When going into Event Viewer I am getting the errors:
All of the configured XML Services for “farm1” failed to respond to this XML transaction. [Log ID: c98c15be]
The Citrix XML Service object was not found: "404" "Not Found".  This message was reported from the XML Service at address "http://mymachinename/scripts/wpnbr.dll [com.citrix.xml.NFuseProtocol.RequestCapabilities]".  This XML Service could not be contacted and will be temporarily removed from the list of active services. [Log ID: 79c6e39]

I have checked and rechecked Terminal Server Licensing and Citrix Licensing. I have uninstalled the web interface server, re-installed IIS, changed the XML port to run on another port instead of “sharing” with IIS and am still receiving these errors.

I am going to try a complete uninstall and reinstall of Citrix 4.5, but am hoping someone may have an idea of what is going on or something else I can try before I completely uninstall and reinstall. (I have put quite a bit of time into creating my policies and publishing applications, so don’t really want to do this…)

Any help would be greatly appreciated!

RE: Citrix PS 4.5 Error"...configured XML Services...failed to respond..."

Here is the issue...
There was one more setting that needed to be changed:
AMC -> WI -> Site -> "Manage server farms".
It said the correct farm name, but was set to port 80.
So when we un-registered and re-registered the XML service there was still that conflict.
Once changed to the port we decided to use (8080), we were able to successfully connect to WI.
It would have saved alot of pain, if this setting was mentioned in the Citrix articles.
