Sccm 2012 Errors

Dear Experts,

In my organization sccm 2012 is installed on windows server 2008. We have a separate server in which SQL is installed. It is also installed on Windows server 2008. All this was installed by another IT guy who has already left the company. Now for the last one month all my clients are showing as inactive. Even i can ping their computers . Also i was getting management point & application catalog website error.Now if i am pushing agents to the client computers it is not getting installed. May be due to management point. With the help of one of the website i uninstalled IIS & then re-installed it again. But now it seems i am getting more errors.
Now I don't want to waste time in troubleshooting . Also my sccm server does not have internet connection.
Please provide me a best solution to tackle this situation.
thinking of installing the SCCM 2012 again. To do this do i need to re-install the SQL server or just need to install the SCCM only.
 i have attached the pics of different errors.

Please help me what to do.
regards,
JCT

Your company must be fairly cheap that they are running SCCM without someone who knows SCCM.

If you want to start afresh then install SQL as well.

Fine! I take my words back.

However you have said "Now I don't want to waste time in troubleshooting ". Why do you want troubleshooting instructions now?

Hi Nagendra,
 
First I thought that i would simply wasting  my time by going into trouble shooting steps.  When i went to one of the sites it recommended never to re-install the sccm server as it will be very complicated. Need to remove all the previous settings from the domain server & so on.

I don't want to take any risk. So i again for the trouble shooting the errors

you can remove SCCM and retain the database if you need to reinstall.

SCCM 2012 is pretty good an providing you with information  and possible solutions on errors, well certainly more so than its predecessor anyway.

Without further information my suggestions would be (aside from my suggestion that you check the Site Status and Component Status messages in the Monitoring workspace for clarification on the errors), would be to check the SCCM Service Account and check the storage space on the SCCM servers.  

Either one of those two could throw up errors all over the shop and if you don't know what to search for, it could seem like the SCCM house of cards is rapidly collapsing around you.
