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:

 

clip_image001

 

Mark Windows Authentication and then click “Providers…” in the right side

 

clip_image003

 

Move up NTLM so it is first.

 

clip_image004

No restart of the server or IIS is necessary. This action must be performed on all management servers with this issue.
