If you getting DistributedCOM errors like:


The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{61738644-F196-11D0-9953-00C04FD919C1} and APPID
{61738644-F196-11D0-9953-00C04FD919C1} to the user <DOMAIN\user> SID (<ID>) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

Resolving error of “is an unexpected token. The expected token is xx or xx . Line xx ,Position xx for Sharepoint 2007

This is a very generic error  fired by .net xml parsers System.Xml.XmlException. In our scenario this error has occured when we tried to change authentication providers for a site.

Usually this error is cuased by a missing charecter or illegal charecter usage in xml files. You know we have so many configuration file in sharepoint. Basic and first look place is that the Web.Config file. Notice that the line and position values and check your web.config file any problem on this location.

For our scenario the Problem Found on 23, 109 the double quots are not supported type for includesubfolders attribute

<PageParserPath VirtualPath=”/*” CompilationMode=”Always” AllowServerSideScript=”true” IncludeSubFolders=”true” />

So the error has fired once sharepoint try modification to web.config for update the authentication providers. So the error source is important to define which configuration file that you have to check.

One of our case we faced with annoying ULS log errors about performace counters. Multiple errors like below filling ULS logs and keep inflated rapidly.

Unable to create system performance counter ComputerName\Memory\Available Mbytes\. The following exception was thrown: System.ComponentModel.Win32Exception: Unknown error (0x800007d0) at Microsoft.SharePoint.Win32.SPPdh.CheckReturnValue(PDH_STATUS status, Boolean throwOnError) at Microsoft.SharePoint.Utilities.SPPerformanceCounter.Initialize() at Microsoft.SharePoint.Utilities.SPPerformanceCounter.NextValue(Int32 retry, Int32 retryInterval) at Microsoft.SharePoint.Utilities.SPPerformanceCounterMonitorInternal.UpdateValue() at Microsoft.SharePoint.Utilities.SPPerformanceCounterMonitorInternal.Create(String computer, String category, String counter, String instance)
Performance Counter OS (pdh) call failed with error code PDH_CSTATUS_NO_MACHINE.

Cause:
Microsoft Sharepoint Timer Service’s account does not have the necessary permissions to access the performance counters on the server.

Backup Error on Moss2007: Object Shared Search Index failed in event OnPrepareBackup, The current operation timed-out after 3600 seconds

11/08/2011 Leave a comment

If you getting error in spbackup.log file when getting backup like:
Error: Object Shared Search Index failed in event OnPrepareBackup. For more information, see the error log located in the backup directory.
WebException: The current operation timed-out after 3600 seconds
Debug: at Microsoft.Office.Server.Search.Administration.SearchSharedApplication.Microsoft.SharePoint.Administration.Backup.IBackupRestore.OnPrepareBackup(Object sender, SPBackupInformation args) at Microsoft.SharePoint.Administration.Backup.SPBackup.RunPrepareBackup(SPBackupRestoreObject node)

Cause:
When performing a backup of a search application, sometimes the operation for pausing the search application fails. In this case, the backup of the search index cannot continue. In that case, the SSP backup is virtually useless. Pre-SP2, the process of backing up the search database will continue. Post-SP2, the failure to pause the search application during a backup process will also result in failure of backing up the search databases, and the search databases will be marked with the same error as the search index component.

Resolution:
Upgrade to Moss 2007 SP2
