Server A was connected to farm A. I uninstalled SharePoint and installed again to create farm B in the same SQL Server.

The SharePoint installation is successfull, however when I try to run the configuration wizard to create the config database (from gui or console) I get the following error and stack trace:

An exception of type System.ComponentModel.Win32Exception was thrown.        Additonal excption information: 
 The data area passed to a system call is too small.
 at   Microsoft.SharePoint.Administration.

In the ULS log, the error that I'm seeing is this:

Ensuring WSS_WPG read access to cryptsvc service.
Failed to open cryptsvc service: 122

After a bit of reserve engineering, I got the excat system call that is failing:

Advapi32.OpenService(sPServiceSafeHandle, "CRYPTSVC", 393216u)

I tried the following to solve my issue:

  • Ensuring setup account rights (SQL sysadmin, machine administrators group, etc.)
  • Reinstalling SharePoint (again)
  • Changing setup account to my own domain account
  • Deleted WSS_WPG local groups
  • Restarting machine, restarting cryptographic service
  • Enabling randomly windows disabled services
  • Uninstalling SharePoint updates and tried RTM release

Not working, what now do except try to wipe and recreate VM?

  • did you perform complete uninstall the sharepoint from server?also make sure following permission for wss-wpg technet.microsoft.com/en-us/library/cc678863.aspx#Section5

  • @WaqasSarwarMCSE Yes I did a complete uninstall/reinstall from the server. It says on the technet link that the configuration should grant those permissions to WSS-WPG. I must grant them manually to the folders before the configuration is ran?

This was resolved by removing all GPOs on this particular machine and rebooting.
