For many years we’ve been doing the exchange public keys “manually” to resolve the communication issues between ConfigMgr sites.
Sudheesh N just came up with an excellent GUI tool to do this work.
See more details in his recent blog post (Full Post).
GUI Tool to Exchange Public Keys Between Sites (here are some extracts from his blog post)
I had feedback from few of the customers and colleagues of mine that the process of manually exchange of keys as per this link http://technet.microsoft.com/en-us/library/bb693690.aspx
takes time and confusing because of similar steps. So for the same I had made a GUI tool which does this works.
Once you extract the content to a same folder in central server or parent server and run the preinstUI.exe you will get a UI as shown below and you can select the Parent site and the child site.
Once you click on Exchange, the GUI vanishes and you will be asked if you really want to proceed with the exchange and if pressed yes it does the exchange. After the exchange the GUI again pops up.
The steps are logged in the \bin\i386\\preinst.log on the server from you are running and would like this.
Note: Please read the readme.txt before using this tool. And as usual, Microsoft makes no warranties or guarantee’s regarding the applicability of this utility nor does Microsoft support the use of this tool in any way.This is just one of those ‘use at your own risk’ type of things that hopefully you’ll find helpful
