Ok, smells like an issue with the group or with replication between your DC's.

If you run GPRESULT or GPRESULT /R (/R is for Win7) from a command window you will see a list of groups the user belongs to in AD. The group should be there. If not then I would delete the group and recreate it, delete the kixtart tokencache and try again.
