Communicator Web Access Loopback Issues

On the same subject as the previous post, I ran into some more issues with the integrated authentication on CWA. It worked from any PC except for the CWA server itself. If I tried to sign in from the CWA box I’d get the endless Windows authentication dialogs and it would eventually fail. The solution?

I created the BackConnectionHostNames multi-string in HKLM\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0 with a value of cwa.confusedamused.com, my internal CWA host name, restarted IIS and was able to login successfully.

Hi there. My name is Tom Pacyk and this is my small home on the web. I love the intersection of design, technology, and communication, which is a combination that led me to a career in sales and marketing roles at places like Zoom and ServiceNow. They're a bit old now, but I also had the opportunity to publish a couple of books along the way.

Portland, Oregon is home for me, my wife Beth, and our three kids, but I'm actually a Midwestern transplant—I grew up in the Chicago suburbs and went to school at Purdue and Illinois. When I find some free time I'm probably going to concerts, rooting for the Portland Timbers, or working on my Sunshine Burn Photography project.
