I have seen this issue several times, but as I always forget it after I’ve fixed it, I decided to make a blog post about it.
As far as I have learned this issue is due to a Kerberos double-hop. But, fear not! The solution is pretty simple:
Open IIS Manager, go to Operations Manager and click Authentication:
Mark Windows Authentication and then click “Providers…” in the right side
Move up NTLM so it is first.
No restart of the server or IIS is necessary. This action must be performed on all management servers with this issue.
