I was facing too many issues with my SharePoint. After too many hit and trial, I decided to unprovision/detach SharePoint and then again attach SharePoint.
I then decided to run the SharePoint Configuration wizard to perform the above operation. After 3rd step it has given me error to ask me check log file where I found nothing. OK. Then I decided to use the great PowerShell. I used the following cmdLet
Disconnect-SPConfigurationDatabase -Confirm:$false
It throws me invocation error. After this, I decided to go with stsadm command and I ran the following script:
psconfig.exe -cmd configdb disconnect
Wow, It has taken only 3 steps to disconnect from SharePoint configuration Database. I don’t know how many SharePoint users agree with me, But I would say Remember Basic. Please Microsoft, Don’t remove this tool in near future.
