Domain users automatically logged off

I’m not sure if I saw good day to the community, but my story line goes like this:

I have just finished preparing a windows 7 64bit computer by following all the best practices of doing sysprep as a final step before capturing the image.

And then I deploy the image to about 50 computers in the lab.

And I manually joing the computers to the domain.

I can loggin locally without any problems, but when I use my domain account it then logg me off automatically.

I tried with diffrent users and I get the same problem.

I hope I will be assisted, especially by those who went through the same problem and successfully resolved it.

Thank you in advance
