now to add second server build server 2012r2 name adfs2
export communications SSL from adfs1 and import in adfs2
run wizard for new install and add to farm ?
Basically your describe steps are right.
Did you create a FARM when you set up the first AD FS server?
we have WID no SQL db
That is no problem. WID supports up to +- 20 AD FS instances.
What about Token - encrypting / signing situation ?
Export and import the required ssl certificate(s) from the first AD FS serverbefore you start the configuration wizard on the second AD FS server.
Note: It is recommended to use a hardware or vitual load balancers for your szenario. The Windows LNB ist not right product for it.
