HI all, Have followed the example of chained gateways at https://blogs.technet.microsoft.com/momteam/2009/12/08/how-to-link-multiple-gateway-servers-together/
[https://msdnshared.blob.core.windows.net/media/TNBlogsFS/BlogFileStorage/blogs_technet/momteam/WindowsLiveWriter/HowtolinkmultipleGatewayServerstogether_95E6/image_26.png] I have a CA where my SCOM 2012 R2 servers site in an AD domain. Gateway 1 is in another domain and has the CA and a Ops Mgr Certificate installed and is in comms - All OK Gateway 2 has the CA certificate and a OpsMgr certificate issues by the CA. My question Is this I am getting Event 20067,21002 are being reported with suggest the OpsMgr certificate on GW1 is not trusted by GW2 even though they are both issues from the same CA. Therefore, do I need a certificate (what and where) for GW1 on GW2?
