WSUS: Unexpected error when choosing “All Updates” view

Ive got a strange and annoying problem with WSUS.

All the views I have created work fine, but the “All Updates” view which is a standard part of WSUS desn’t work, MMC crashes and reports:

Error: Unexpected error

An unexpected error occured. Please contact your system administrator if the problem persists.

The WSUS administration console has encountered an unexpected error. This may be a transient error; try restarting the administration console. If this error persists,

This is the error :

System.ArgumentOutOfRangeException — Value of ‘-4,29159’ is not valid for ‘FillWeight’. ‘FillWeight’ must be greater than 0.

Parameter name: FillWeight



Stack Trace:

   at System.Windows.Forms.DataGridViewColumn.set_FillWeight(Single value)

   at Microsoft.UpdateServices.UI.SnapIn.Pages.BaseListPage.GetColumnHeader(Column column)

   at Microsoft.UpdateServices.UI.SnapIn.Pages.BaseListPage.PopulateColumnHeaders(List`1 columns)

The solution is :

  • Open the IIS console
  • Expand Web Sites and right-clicked on Default Web Site and selected properties
  • Click on the ASP.NET tab and change the version from 1.1.4322 to 2.0.50727 and clicked OK
  • Open a cmd prompt and cd’d to: %windir%\\framework\v2.0.50727
  • Run aspnet_regiis –I
  • Run iisreset /restart
  • Important! : Navigate to %appdata%\microsoft\mmc, and delete the wsus file
