Swap Front End and Back End IP Addresses?

Posted on 2007-11-28

After one gotcha, the FE/BE topology is up and running.  However, I must swap the IP addresses of the FE and BE servers.  I have looked on MS site, but don't see anything about hazards of swapping FE/BE IP addresses.  Is it as simple as it sounds or is there something I need to know before swapping the IP's?

The problem you are going to have is the swap. You will need to disconnect one while you change its IP address - or use a third interim IP address. I would suggest that you reboot both servers after changing the IP address.

Since I didn't here anything for 6 hours, I decided to do it the safe way.  I used a third interim IP address and the swap was uneventful except that Exchange ActiveSync isn't working anymore.  I get the typical error code on my device.  I don't have Enforce SSL checked and I don't use Forms based Authentication, so I am at a loss.  I can browse to http://mailserver/oma and https://mailserver/oma and it works just fine.

Any ideas?

To get EAS to work, did you set up the server like MSKB 817379? If so, have you changed the restrictions on the connection that it outlines?

I followed everything in that article, but no help.  I broke down and called MS support.  It turned out that when I first tried to get Exchange Activesync working a year or so ago I had major issues and called MS support then.  To get Exchange Activesync working, the MS tech added a reg key to make it work.  However, that key only works for stand alone Exchange environments.  I removed the key, rebooted and all was well.
