Upgrading SEP 11 managed clients to SEP 11 MR2 - clients wont connect to Management Console

We upgraded to SEP MR2 and are in the process of upgrading clients.  The problem is once the clients are upgraded they will not connect to the Management Console unless the previous version of SEP is completely uninstalled and the new version is installed.  Anyway to keep from uninstalling on every client computer before pushing the MR2 package?
1 Solution
Question, did anything like the server name or the default group name change during the upgrade? SEP uses a file called sylink.xml to keep track of all the settings etc. I would try copying the xml file from a known working machine to one having the problem. It will be located in \program files\Symantec\Symantec Endpoint Protection. (You may have to unhide files to see it, not sure).

Try Resetting ODBC connection, I suppose the SEMP is not listed there.
Wgclark, I had the same problem with my SEPM MR2 upgrading.
One thing is to replace the sylink.xml file in the clients pc's. as CorruptedLogic says, but anyhow you have to preplace the file after stopping the service from the command line.
run CMD and go to c:\program files\symantec\symantec endpoint protection and then type smc -stop. replace the file taken from the management server (better) and in the same dir type the command smc -start.
This should fix the problem. But, by my bad experience with SEPM 11 this issue wast the only one. Once clients were all connected to the Management server and uploaded policies from the server regulary, the next problem was with the definition updating of the server in which telling the truth i made the best i could but didn't fix it  anyway until i updradet from SEPM 11.0 MR2 to SEPM 11.0 MR2 MP1. my best suggestion to fix your problems is to upgrade directly to SEPM 11.0 MR2 MP1 to save your time.

Hope this would help.

Cyber Threats to Small Businesses (Part 1)

This past May, Webroot surveyed more than 600 IT decision-makers at medium-sized companies to see how these small businesses perceived new threats facing their organizations.  Read what Webroot CISO, Gary Hayslip, has to say about the survey in part 1 of this 2-part blog series.

I have the client loaded on the SEP Management server and it is good to go.  I compared that sylink.xml to other users that do not connect to the server and it is the same.  I installed the software on a new laptop and it does not connect to the management server now either.  I can not get any clients to connect to the management server.

I don't think what you are trying to do is really possible..!
running two version of SEP will probably interfere ..!
wgclarkAuthor Commented:
Running the client antivirus on the Management Server will interfere?  They are both the same version - MR2 MP1.  Regardless, it was broke before.  I am going to roll back to the last version that worked for me the initial release version and try to go from there.
