Help Reintalling WSUS

Hi All,

Been having issues with reinstalling WSUS - Every time I'm running the installer it keeps erroring and referring me to a log file located in windows - Here is what is shown in the log -

2009-07-06 20:57:16  Success   MWUSSetup          Validating pre-requisites...
2009-07-06 20:57:33  Error     MWUSSetup          CSqlConnection::Open: Failed to open SQL connection to instance LSBD-MK-MANAGE\SCE (Error 0x80004005: Unspecified error)
2009-07-06 20:57:33  Error     MWUSSetup          CUpgradeDriver::PerformPreSetupActions: Failed to open connection to SQL instance %computername%\SCE (Error 0x80004005: Unspecified error)
2009-07-06 20:57:33  Error     MWUSSetup          CSetupDriver::LaunchSetup: Failed to perform pre-setup actions (Error 0x80004005: Unspecified error)
2009-07-06 20:57:33  Error     MWUSSetup          CProgressManager::EnableCancel: GetDlgItem returning error (Error 0x80070578: Invalid window handle.)


Hope that someone can help. Thanks in advance

You may have not fully removed WSUS try the below.

1. Download the SDK to obtain MSIZAP

   http://download.microsoft.com/download/e/9/d/e9d80355-7ab4-45b8-80e8-983a48d5e1bd/msicuu2.exe

2. From a command prompt, type:
MSIZAP T {2C0D7E35-EE6E-4DC7-BA13-2C68AEDEB59D}

3. From a command prompt, type: sc delete wsusservice

4. Again, From a command prompt, type:

    MSIZAP T {2C0D7E35-EE6E-4DC7-BA13-2C68AEDEB59D}

5. From a command prompt, type: iisreset

The MSIZAP switch "T" removes all info for given product code

P.S.
For WSUS 3.0: MSIZAP T {2C0D7E35-EE6E-4DC7-BA13-2C68AEDEB59D}


For Microsoft SQL Server 2005 Embedded Edition

1) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
     Edit the "InstalledInstances" value and remove "MICROSOFT##SSEE"

2) Remove the "MICROSOFT##SSEE" subkey under
     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

3) Remove the "MSSQL.2005" subkey under
     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

4) Rename the following folder:
      \%Windir%\SYSMSI\SSEE\MSSQL.2005\MSSQL\Data  to   \%Windir%\SYSMSI\SSEE\MSSQL.2005\MSSQL\Data.old

  (If \MSSQL\Data lock , you can removing the "Windows Internal Database" from Add/remove programs)
