Change in User Information in AD, not getting Sync with SharePoint after Profile import

Few days back, my client started facing an issue.. when there was a change in user information in AD (Active Directory)... SharePoint was not able to synchronize these changes..

Actually for some users, their login id & display name get renamed in AD.. So when they were logging in into the SharePoint portal with New login id, Portal was displaying still the old name... as "Welcome (old display name)"

Problem Description

Consider the following scenario.
You create a user account that is named User A, and you add User A to a Microsoft Office SharePoint Server (MOSS) 2007 Web application.
You import the user profile information in a SharePoint Server 2007 Web application, and the profile synchronization timer job runs.
User A logs off from the MOSS Web site.
You use Active Directory Domain Services (AD DS) to rename User A to User B, and you also change the information for the Account name.
You import the new user profile information, and the profile synchronization timer job runs.
User B logs on to the MOSS site.
In this scenario, when User B clicks My Settings in the MOSS 2007 Web application, the User name box and the Account name box still display the information for User A.


Solution

To resolve this problem, open a command prompt, type the following command, and then press ENTER:

stsadm.exe -o migrateuser -oldlogin -newlogin -ignoresidhistory

Important Run this command only on user accounts that are in the same domain. Otherwise, you may experience permission problems.

This command automatically updates the account name, and the command maintains the correct permissions for the account. To update the user name for the user account that is updated, follow these steps:
Log on to the MOSS Web application.
Click My Settings, click Edit Item, and then change the user name.

Windows SharePoint Services Web Application Required on Farm, not running Starting

I used to find, services are getting stuck under SharePoint Central Admin. This time, it is "Windows SharePoint Services Web Application".



The best way I find to get out of it, is mentioned below,

Step 1. Stop the service from Command Prompt,

Open Command prompt then navigate to 12\bin folder & execute the below command,

stsadm -o provisionservice -action stop -servicetype SPWebService

Step 2. Reset IIS

Open Command Prompt & execute,

iisreset

Step 3. Start the service back from Command Prompt

open Command prompt & navigate to 12\bin folder. Now execute the below command to Start the service again,

stsadm -o provisionservice -action start -servicetype SPWebService

Here it goes. service will start after executing above command. If still, you are not able to Start the service... Shut down your system for 10 minutes & then try the above steps again. It will work.. Cheers :)
