SCCM 2012 Client Certificate (PKI) Value is None

Operating system deployment slowness at remote sites.

Up until last week Task Sequence was taking approximately 9 hours to finish the image at remote sites; now it’s taking a little less than 2 hours. Below is the detailed explanation of the issue and the fix.

While checking the SMSTS.log and DataTransferService.log logs on TEST001 (Testing machine) (this one took 9 hours to finish), I found out that the packages and applications were getting downloaded from One of the Primary site (PRI01). We wanted all the packages and applications to be downloaded from Remote distribution point (RDP01) as this server is local on remote network (RN01) and has all the required packages/applications. I looked at the boundaries on PRI02 site (RDP01 belongs to PRI02) and everything was correct. I tried to redistribute packages, delete and re-add the boundary and boundary group for Remote office, but none of these fixed the issue. After struggling for a bit, I decided to check the boundary on PRI01 site.

Creating Chrome extension package in SCCM 2012

Last month I was asked to create an SCCM package for chrome extension - 'RingDNA' (Intelligent dialer for salesforce) .  Well , at first place , it looks stupid, creating an package for chrome ext. which is just one click away installing from chrome web store, anyways , I still gave a try.
Steps:- 1. First of all, I downloaded the .crx file using this Chrome Extension down loader -
2. In the Registry, I created a new key under the Extensions key with the same name as the ID of your extension. If you don't know the ID, follow these steps to note the ID-             a) Install the required extension manually             b) Open settings from chrome menu bar> click on Extensions> enable developer mode                         from top right corner, will show the IDs for all installed extensions.             c) Alternate way, open C:\Users\<currentuser>\AppData\Local\Google\Chrome\User                       Data\Default\Extensions…

How Symantec disabled Corporate Wifi on some of the machines.

Issue - Today , some laptop users started reporting as they are unable to connect to corporate wireless after System Center Endpoint protection(SCEP) installation took place. I found, most of the laptop users were having this issue.  Troubleshooting done - I immediately uninstalled SCEP but that didn’t help , tried removing Wi-Fi profiles under the path ‘C:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces\Interface’ but that didn’t help too.
Error- When checking event viewer, the only error that showed up is as follows 5 times in a row.          “Error skipping EAP method DLL path name validation failed. Error: typeId=25, authorId=0,vendorId=0,vendorType=0”, This error indicates a registry or missing corrupt file issue.
EAPHost is a Microsoft Windows Networking component that provides an Extensible Authentication Protocol (EAP) infrastructure for the authentication of following protocols such as802.1XandPoint-to-Point(PPP).
Cause - Symantec didn’t uninstall properly caused this issue.

Error Message – “SQL Server has encountered the following error: The NT Service: MSSQLSERVER could not be started, error code 0x884B20001”

Troubleshooting done – 1.Some blogs were suggesting, it’s a permission issue, immediately we logged in to the server with different admin account and tried to install SP3 but it threw the same error. 2.When we checked the “installed updates” under “programs and features”, we found that SP3 got installed. We tried to remove installed components of service pack 3 but again it was giving “Access Denied” error. 3.We tried to repair SQL instance but again we came across “Access Denied” error. 4.We checked the summary.txt (C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log) and observed following logs:

Final result:  The patch installer has failed to update the following instance:. To determine the…
