-SharePoint 2010 Ent.
-Windows w2k8 R2 Ent x64.
-Using SQL Server 2008 R2 x64-The local accounts I added to SQL Server both have the rights to create dbs (dbcreator and also sysadmin)-Windows Firewall is off (this probably isn't a factor)-I checked the version of Geneva Framework I have in assembly and it was 188.8.131.52. anyway, but I uninstalled this via Add/Remove, rebooted server, installed again, no luck.-At the farm credentials stage, I am using the following credentials: Name of Windows account I am using (eg Hany, but not ComputerName\AccountName), and the password to login.-When I installed SQL Server, I added the Administrator local account and my named local account but also with mixed auth and a password.-I am running a fully updated version of Windows Server. I haven't installed the other updates mentioned in various posts.
I faced this problem and I managed to solve it through the following steps:
· Make sure that your machine name is limited to 15 bit to be within the NetBIOS naming limits.
· Makes sure that the local windows accounts you are using to run the command as well as the perform the database access account is are using the following format:
MachineName\accountname, where the MachineName is your new machine name
