I've installed Lync standard edition with: 1 front end server + 1 edge server. Lync web service running on 2nd NIC on front end server. When two external client (different LAN) trying to share a PPT slide: sender can see notification about uploading success and see the slide, another one got an error:
"This slide couldn't be downloaded. Please contact...., Error reason: Name not resolved"
. I'm trying to google but nothing found about this error. Another features: A/V conf, desktop sharing, whiteboard still works. I can see Lync connected to front end server but still have notification about not success sync corp address book. Any idea?
TIA,
giobuon
I've solved my problem by doing these step:
Get right permission for share folder on front end.
Reconfigure DNS record for external-web (you can get its name from topo builder)
Open requirement ports.
One thing I got from this "days wasting" is RTFM :(
Yes, the web sharing goes through the Reverse Proxy on your front end pool. External-web ports 4443 and 8080 on the server side, 443 and 80 on your router side. And yes it does need a public cert.
Glad you were able to figure it out!
