SEP showing server offline
Recently I had to do a reinstall of SEPM 11.0.6005.562 (on windows sbs 2008) after this obviouisly none of the SEP clients (all on windows 7) would connect so I created a new domain addded the old domain ID and recreated the old groups. After a refresh all the old clients showed up. However, on the client machine it says that the server is offline and in SEPM it has the computer off logo beside the clients. I can't replace the sylink file as no clients are currently connected. Also when tried to reinstall SEP from the SEPM it doesn't work either. The only thing I can guess it would be is that it is the folder permissions of D:\Program Files\Symantec\Symantec Endpoint Protection Manager. I don't think it is the firewall as none of those settings have been touched since symantec last worked
Here is an error log from one of the clients as well

Help would really be appreciated as I am stuck at a loose end!
