I have approximately 700 systems in my organization. A few hundred of these systems are reporting as offline when I personally confirmed on the client itself that they are online, and convinced that they are connected and reporting to the right server.
We run Vist 32-bit and Win 7 32-bit. The vista systems are connecting without issues. 90% of the Win 7 systems are not.
I have tested replacing the sylink.xml file and connecting on the client through help - troubleshooting - connection status that solved nothing.
I have rebuilt the server, several times. I even rebuilt it and manually installed each of the 700 systems. That also solved nothing.
I have tried SEPM with an embedded database and with an SQL database. Neither made a difference. Currently we are remaining on the SQL database.
I have verified connections to the database and it works, which makes sense because all the vista systems are working.
I have tried installing SEP 12.1.1000.157, SEP 12.1.1101.401, SEP 12.1.2015.2015 and none of the successfully report.
Ghosting these systems is not feasible as there must be an actual solution and I cannot insist that a few hundred systems get rebuilt.
I have tried every solution in the SEP Clients Not Connecting technical solutions page that Symantec put out.
I have tested the network and there are no issues within it that I can find.
I have tried linking it through active directory and it is still not locating those few hundred that are online, it is still linked to Active Directory.
I turned debugging on for one of the systems and returned this one interesting tidbit in the log:
2013/01/02 11:45:06.980 [3144:2388] <mfn_PostApplication>===SEND EVENT_SERVER_REQUIRES_CLIENT_APPLEARNING ===

Also, my SEPM is currently 12.1.2015.2015 and this has been an issue even when it was on all the other versions listed above.
Looking for a solution. Thank you.
