Hello.

I have some problem with Software Center on client computer.

Software Center stops refresh available software and stop install required applications. It look like it is got suspended. Even if I restart computer Software Center doesn't work.
In Configuration Manager Console that computer stops respond and in a few days I get information that it does not have client.

I saw this problem gets often in Windows 8.1 and less often in Windows 7
Only one solution is to run ccmrepair.exe from C:\Windows\CCM

It is any other solution to fix this problem ?

Never seen that happening. What version of ConfigMgr are you using?
Plus: the only way that the client flag will be flipped from "client = yes" to "no" is by running the 'clear install flag' site maintenance task. This will only reset the flag if the site did not receive current discovery data from the client. Have you examined any client-side logs so far? The eventlog?

I use SCCM 2012 R2 CU4

Which log file i should analyse in C:\Windows\CCM\Logs is many log files.

Hi,

Please check client's health: CcmEval.log

Check LocationServices.log and CcmMessaging.log.

Ok I found this information on log files on one of brick Configuration Manager client:
Computer actual connect to our network.

Can your machine contact MP?

Try this on your browser - http://<ServerName>/sms_mp/.sms_aut?mplist

I can connect to MP this site is opening on every computer.

Now I test computer with Winsdows 8.1
It is very strange when on computer log in standard user SCCM client stops working sometimes on Windows 8.1. I have admins rights on our domain when I log on on that computer and restart it several times the SCCM client start working again. It start install software again and in Configuration Manager Console inform that client is installed again.
