In my organisation Sccm 2012 is installed on windows server 2008 server. For the last one month the console shows as inactive clients. Also its shows client type as "none" & client as "No". Then after few days its shows client activity as "Active". Again now the same problem i am having. Previously i was having windows 7 32bit & windows 7 64 bit device collections. suddenly windows 7 32 bit started showing no clients. reconfigured the device collection for windows 7 32 bit but still showing no clients. then i deleted the device collections for windows 7 32bit & 64 bit.Made it single as windows 7 collections. Client activity showing inactive. did install client from the console but of no use.
I have attached few images of it.
Please suggest me a remedy for this issue
