The number of discovered DPs(including Branch DP and Multicast) is 0

Recommended Posts

I have been trying to determine why our VPN clients are having trouble with downloading content and receiving this error in the CAS.Log 'The number of discovered DPs(including Branch DP and Multicast) is 0'.

 

I have checked the client IP addresses and they are in scope of a boundary. The boundaries are 'fast' connected. The applications are on the DPs and successfully verified (Content validation). Also if a client comes on site the content downloads and installs AOK.

 

The main difference on VPN is that there are two IP addresses. (Local private IP and VPN Address)

 

We added boundaries for the private addresses because in the past VPN clients would not download content and now its happening again.

Excerpt:

"If a Configuration Manager 2007 client has multiple network cards (possibly a LAN network card and a dial-up modem), and therefore has multiple IP addresses, the IP address used to an evaluate client site assignment is nondeterministic."

 

Is this still viable in 2012 R2 SP1? Does this play a role in content downloads?

Yes this is still true in CM12 and CMCB. The simple fix is to always all content to be downloaded on slow boundaries. You sett this one each package, application, SU, etc.
