WSUS, IIS and IPv6
Recently, I have been playing around with Windows Server Update Services (WSUS), which is responsible for sending Windows Updates to all machines in my domain. WSUS hosts its updates on an IIS (Internet Information Services) website.
After a reboot today, I discovered that I couldn't connect to the WSUS administration console - being given the error:
"
Error: Connection Error
An error occurred trying to connect the WSUS server. This error can happen for a number of reasons. Check connectivity with the server. Please contact your network administrator if the problem persists.
Click Reset Server Node to connect the server again. "
Nothing I tried, after many searches and forums seemed to help me, until I looked in the IIS error logs.
Here, I noticed that a lot of 400 errors with IPv6 addresses (I had enabled IPv6 across my network yesterday). I then remembered that I had bound the IIS site to my internal IPv4 address (as I am anticipating this machine becoming a gateway, and didn't want any Tom, Dick or Harry stealing my bandwidth).
For some reason, IIS doesn't support binding to an IPv6 address, only IPv4, so I was left with no option but to set IIS to listen on the "(all unassigned)" addresses.
This then enabled me to connect and continue playing with WSUS.
I hope this helps anyone who may have come across this issue. IPv6 may have been the cause of the RPC faults I have been experiencing too... I may have to investigate that further.
