Hi,
I have a Lync 2013 platform with two FE Pools in a paired relationship. When failing over from one pool to the other, all functionality works and clients (desktop / LPE), sign back in OK. My issue is that address book searching on an LPE device no longer works following the failover and is immediately restored on failback.
My gut feeling is that the LPE devices are still attempting to query the address book using the FQDN associated with the web farm of the failed pool, as this is what is provided by DHCP. I can see in a desktop client that the URL's reflect that of the secondary pool, but these are given dynamically when the client connects into the pool.
Has anyone had any experience with this or had a similar issue?
I'm wondering if I could update option 43 at the point of failover and set it to the FQDN of the web farm of the secondary pool to force traffic to the right location.
