I have and issue with making Lync Clients to be able to log into lync through WIFI I have done all configuration on Aruba regarding the Lync and when client try to sign in lync it says we can not sign you,verify the certficate and I found this error on logging :
May 27 01:54:54 <web_cc 354023> <ERRS> |web_cc| web_cc_callback: URL lookup failed : lyncdiscoverinternal.work.home.com
and when I try to check for this address it is know by by controlller and it equal to the Lync server IP
so what may be the issue here?
