I currently am running WIndows Server 2008 (32bit). Sharepoint 3.0 was configured and working flawlessly on SQL2005 along with an instance installed from our CRM system (ACT). Upon upgrading ACT, the tech rep from ACT completely removed SQL2005, and during the upgrade it installed a new instance of SQL2008R2 for ACT. Unfortunately this completely removed SQL2005 and our Sharepoint DB. Unfortunately there is no backup to go to so we are at square one with NO data.
I have tried repairing, uninstalling, re-installing Sharepoint, and still no luck. When performing a basic install I get the error (configuration database not found, and a MSSQL$Microsoft$##SSEE error). I tried an advanced sharepoint install and it made it further, but threw an error later in the configuration steps saying there was no database to install to or connect to. The only instances I see in SQL2008R2 management console is my ACT instance.
I am completely locked up right now with no way to proceed in installing and configuring a new Sharepoint site/database. I attached the error log when trying to configure the Sharepoint DB as well. Sharepoint-Error-Log-PSCDiagnost.log
