Sharepoint 2010 Timer Service error code 1069

On my local SharePoint server, Timer Service gives me an error "The service could not be started due to logon failure".

Initially I thought that, there is a need to enable some service from the Central Administration. Later realized that the issue is in the service itself.
The issue is fixed after setting of proper password within the service properties.

Fixing error "Cannot generate serialization assembly"

Recently on my development machine I faced this error in Visual Studio. The error occurred at the build a project, and that project is already in use on the local machine.

Now, the problem here is, out the error message nothing clearly come out. After further research I found that the output dll is already present in GAC and after removing that dll, the project showed successful build.


Cheers!!
