Here is one thing to check that might help - make sure the IIS App Pool is running a user that has access to SharePoint and SQL.

Hope that helps...

I don't know exactly how long it will take, but it could be upwards of 15 minutes or so, depending upon the type of system it is running on. The article looks very good though.

Usually after a restart the service account can be an issue. I know you said it works fine access SQL, but check the account anyway in AD to make sure it is not now disabled or the password has expired. I know, it is set to never expire and the account is enabled, but never hurts to check I suppose. It has bitten me before.

Good luck...

Can you share the result what happens when you browse central admin site from IIS directly?
Try to re-enter the password under the identity section of the site for the account which is running the site application pool.
Do an iisreset and let me know the outcome.

there were missing registry keys, maybe from some .NET update ?

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework’, create a new ‘DWORD (32-bit) Value’ named "LoaderOptimization" with a value .

‘HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework‘, create a new ‘DWORD (32-bit) Value’ named "LoaderOptimization" with a value 1.

Glad you got it fixed. The updated made changes, but they didn't kick in until the restart. Been there, done that. Don't you hate it when that happens!

Good find...
