Hello,
We are running 12.1.6 MP4 (12.1 RU6 MP4), MAR 2016. We just recently upgraded to this new client. Servers that have not been upgraded still have the SYLINK entry in their Registry. Upgraded servers are missing the entry.
All the clients appear to be communicating with the SEPM just fine as evidenced by the green dot on the client and no problems in the SEPM.
I tried re-importing a Sylink.xml file, but the entries were not re-created. Any help much appreciated.
