I am having an issue with SQL 2008 R2 express. I have a need to create a second instance (one is already running and in use) when I try create it I run through the setup wizard. I have setup a windows active directory account to be used with this database and I set it to windows authentication. Everything seems to go well but then I get an error saying:
"The following error has occurred: the specified account already exists" only option is to click OK then everything fails. I have tried with the default network / system account and get the same error. I have also tried with other Windows accounts and get the same error. I have rebooted the server to no avail. Everything else is working perfectly on this server. It is a fairly new fresh install. Its only job is to be a SQL server for a document management system. This is all working well but now we are looking to add a workflow which I would like setup on its own SQL server instance. The document management software is Laserfiche. I will add screenshot of error. Does anyone know which account "already exists" or how to resolve this?
