SP1 Cumulative update 4 stuck on "Downloading information"

Question

I have a server that is attempting to install the SP1 CU4 update for SCCM 2012 client but never succeeds. If you go into the Software Center on the machine, the status is continually stuck at "Downloading information".
I tried to force it by copying the installation package to the server and running the command line option specified in the package properties (msiexec.exe /p configmgr2012ac-sp1-kb2922875-x64.msp /L*v %TEMP%\configmgr2012ac-sp1-kb2922875-x64.msp.LOG /q REINSTALL=ALL
REINSTALLMODE=mous). The installation ran and appears to have been applied successfully (the version of the client shown in Control Panel --> Configuration Manager Properties went from 5.00.7804.1000 to 5.00.7804.1500) and the Software Center icon
went away afterwards.
I was just finishing up congratulating myself when I received a notification from the Software Center again that software was being installed. I opened up Software Center, and there it was again - SP1 CU4 stuck at "Downloading information".
I've rebooted several times, but Software Center continues to pop up every time with same status.
One thing I should note, I recently migrated my SCCM server to new hardware and this "problem server" was installed after the migration. Prior to that, all of my other servers received the SP1 CU4 without issue. Both servers (SCCM and
problem server) are Windows Server 2012 R2.

Thanks for the reply Anoop.
I checked the logs mentioned in the article, and everything looks fine as far as I can tell up until "Step 5: Tracking the Content Download."
In the "DataTransferService" log, there are numerous error messages:
[CCMHTTP] ERROR: URL=http://server.domain.local:80/SMS_DP_SMSPKG$/RIC00009, Port=80, Options=224, Code=0, Text=CCM_E_BAD_HTTP_STATUS_CODE
Error sending DAV request. HTTP code 404, status 'Not Found'
GetDirectoryList_HTTP('http://server.domain.local:80/SMS_DP_SMSPKG$/RIC00009') failed with code 0x87d0027e.
So looks like I have an IIS problem? I opened IIS Manager, and browsed to the directory on the DP server. In that directory, I see several other directories (DataLib, FileLib, PkgLib). I assume my package information should be in the "PkgLib" folder, but
inside that folder are just four .INI files (RIC00001.INI, RIC00002.INI, etc). There is no RIC00009.INI file, maybe that's my problem?
I also went into Config Mgr Console --> Administration --> Distribution Points, went to the properties of my Distribution Point, then to the "Content" tab, highlighted my package and clicked "Validate". Not sure though what this accomplishes.
