Thanks for sharing this  It helped a lot  The one difference in my applicationHost config was               lt add name  SharePoint14Module  image  C  Program Files Common Files Microsoft Shared Web Server Extensions 14 isapi owssvr dll  preCondition  appPoolName SharePoint Central Administration v4 bitness64 SharePoint - 80    gt    Note the multiple semicolon seperated entries  This is probably because I have a single box install of SPS

Can You Please try this    Check the web site properties in IIS   Under home directory tab  check the application pool value   Verify that all SharePoint services are started  If the application is not started do the following  I think this error might occur because of changing the service account password       You may need to change the new password to application pool     1 Click the stopped application pool      2 click advanced settings      3 Identity - click the user to retype the user      4   Application Pool Identity dialog      5 click set -  manually type the user name and password       Then restart the server

I had trouble finding the applicationhost config file   It was in c  windows System32 inetsrv   Server2008  or the c  windows System32 inetsrv config   Server2008r2    After I changed that setting  I also had to change the way IIS loads the aspnet filter dll   Open the IIS Manager  go under  Sites    SharePoint - 80   in the  IIS  grouping  under the  ISAPI Filters   make sure that all of the  Executable  paths point to    Microsoft NET Framework64 v         aspnet filter dll   Some of mine were pointed to the  Framework   not 64      You also need to restart the WWW service to reload the new settings

I agree with Beytan Kurt   I had 503 thrown for both the Central Admin site as well as the SharePoint landing page  In both cases the Passwords were expired   After resetting the password in the AD  and refreshing the Identity  CA worked but the SharePoint landing page threw a 500 error    It turned out that the  Net Framework Version was set to V4 0  I changed it to V2 0 and it worked    Remember after each change you need to recycle the appropriate app pool

I was having a similar issue with a customer and none of the posted resolutions did the trick  I granted the  Log on as a batch job  permission via the Local Security Policy and that finally made the Central Administration web page come up properly

It can also happen if your password policy or something else have changed your password in case your appPools are using the the user with changed password   So  you should update the user password from the advanced settings of your appPool throught  Identity  property   The reference is here

1  Ensure that the enable32BitAppOnWin64 setting for the  SharePoint Central Administration  app pool is set to False  and the same for the  SharePoint Web Services Root  app pool  2  Edit applicationHost config   bitness64 being the magic word here

Sometimes Web config of the application ends up in an unconsistent state  duplicate declaration of http handlers  etc  To check which line in config is causing the error open IIS Manager and try to edit the handler mappings  it will display you the error line if there is such an error in web config   Strangely such errors do not get logged in Event viewer or ULS

I had the same issue but the password was good and  Log on as batch job  alone was not sufficient   Check that the IIS application pool identity account or group has both the  Log on as Batch Job  permission AND that it can  impersonate a client after authentication    To change these settings perform the following steps on the web front end server    Start Run type  secpol msc   Find  Security Settings Local Policies User Rights assignment Add user or group to  Log on as Batch Job   Check group membership of service account  in Active Directory  if a particular group is being used for this purpose   Find  impersonate a client after authentication  and add the application pool identity  Reboot the server    You should be able to access the site

The selected answer posted here solved one problem  but another is that you ll have to change the app pool to use  Net 2 0    SharePoint 2010 uses  NET Framework 3 5  not 4 0    The SharePoint 2010 app pools should be configured as  NET Framework 2 0 using the Integrated Pipeline Mode    source  http   social msdn microsoft com Forums en-US sharepoint2010general thread 4727f9b4-cc58-4d86-903b-fabed13da0ff
