When i reviewed the ZTIWindows i found this: This is despite telling it to connect to my wsus box. Conference Failure Exception: The operation failed due to a response from the server.
Googled for hours, found nothing – this worked for me. We did traces, reinstalled conferencing service, the conference attendants, published and republished the topology etc etc, eventually some kind of timer tripped at Microsoft support in India and they brought out the big guns did a 25mb trace on the call join and went through it line by line.At this point the engineer told me that the issue was with the certificate on the FE server, he showed me the certificate that we had (just) issued to our freshly minted Lync 2010 server and the certificate signing algorithm was RSASAA-PSS, apparently Lync ONLY works with certificates issued with the sha1RSA algorithm.Since last issuing Lync certificates we have upgraded our enterprise PKI to 2012 R2 which it seems by default issues certs signed with RSASAA-PSS.Yes – this also affects Lync 2013 according to the support team.There is no easy way aside a file copy and paste to move virtual machines between 2008 R2 and Hyper-V 2012 R2 with the native tools.You can move from 2008 R2 to 2012, but not to 2012 R2.
I have found the easiest, quickest way to do this is to use the VEEAM hyper-v backup/restore utility.
It requires a agent on the servers you are moving VM’s from and to and seems to work very very well, quick also with up to 1.7 compression and a good backup on the host you use for the transfer.
Veeam Backup/Recovery When you restore your 2008 R2 VM it updates the WMI, adds it to the cluster (if you want that) and brings it back online.
Well worth a look if you want a painless migration.
Following this great technet KB, i had issues applying WSUS updates to a reference image.
The pre and post application installation tasks were not running properly, although they didn’t error they failed to actually do anything.
