I have been pulling my hair out for two days trying to get WHMCS on my W2K8 64-bit VPS. I finally manged to do it.
The DC will be reloading me from scratch so I can start over. I added and removed things so many times I felt I needed a fresh start.
When I re-install I will be documenting the steps and was thinking of writing a "how to" if anyone is interested in it.
Does port 9002 (the ES server port) need to be opened for incoming and outgoing on both the DNP Enterprise Server server and also on the WHMCS server?
I keep getting a WSDL error although I can browse the URL and see the XML.
