All SharePoint Sites Not working After Installed March 2015 Microsoft Patches

Operating Sytem: windows server 2003

Sharepoint Server : Sharepoint Server 2007

DB Server : MS SQL Server 2005

We have several Windows Server 2003 boxes available , and last night, tech admin guys had installed their Microsoft March 2013 Security patches around 12 installed.

This morning, users cannot access sharepoint sites they were previously able to, and are prompted for credentials. When entering their credentials, authentication seems to fail.

Users always frustrating even they has entered correct domain name,user name and password.

But I am an share point admin, I tested the sites inside the server using system account and normal users account, which is working fine.

When i am accessing the share point sites from other laptop or system using normal account, it is keep on prompting credentials.
I checked windows event logs,sharepoint logs and DB logs, we didnt get any clue regarding that issue, so we asked to tech admin to uninstall all Mar 2013 patches installed by last night, he only unistalled two web front end servers and DB servers and AD server. Then i tested again it is again prompting user name and password for normal users.

Solution:

Finally the sites are working for all users, Because Tech admin should forget to uninstall the patches on the two Domain Controller server.

Mainly Uninstall this patches KB 3002657

After that We checked the share point sites can be accessible to all user's without prompting credentials

We also referred the below sites, thanks for your valuable suggestion and gave sleeping time by tonight otherwise ...we might be spent to research for other parameters, my courtesy in the below sites, bcos we found the root cause of the issue for installed  Mar 2015 patches denoted in the below site.

Certificate Validation errors in SharePoint 2013

I got client investigating performance issues – the Portal pages were sometimes taking a very long time to load. Page load times were inconsistent, and the browser would spend a long time “Connecting…”, before content would load on the page. Checking the event logs, we saw a frequent error message:

Error:

A certificate validation operation took 30008.7312 milliseconds
and has exceeded the execution time threshold. 
If this continues to occur, it may represent a configuration issue. 
Please see http://go.microsoft.com/fwlink/?LinkId=246987 for more details.

 I did something similar before and had to generate a cert via powershell. So I done the following in the SharePoint Management Shell:
$rootCert = (Get-SPCertificateAuthority).RootCertificate
$rootCert.Export(“Cer”) | Set-Content C:\root.cer –Encoding Byte

The Certificate file will be saved on the C drive


 Once done I went back into the certificates snap in and imported the certificate into the trusted root certificate authorities. Once done the bulk of the errors disappeared 

Then I added Host entry of the web app port number in that host file entries

Error 1603 installing AppFabric 1.1 for Windows Server 2012

The whole day I am searching and fixing the issues, please do any steps

   1.     Kindly Check the accounts used by the Central Admin application pool
in the  IIS setting, and then check the accounts used by the various SharePoint services (in MMC). They are Windows SharePoint Serivces Administration, Windows SharePoint Serivces Search, and Windows SharePoint Serivces Timer.

   2.     check the time zone and date and time between AD and SQL server, if any changes, please correct it and restart the client machine

   3.     Still if you face the issue, run the following command on client machine

   4.     gpudpate /force

   5.     gpupdate /sync

   6.     Still if you face the issue, rejoin the SQL machine in th domain(in my case, i have rejoin the domain)

    7.     I fixed and got resolution based on first step 1
