SCCM - which logs to check for application deployment issues?

We're running SCCM 2007 SP2 on Windows 2008 R2 and have managed to create a package and program which is successfully advertised to a Windows 7 workstation. The deployment job starts and the install.exe can be seen on the client machine but does not progress beyond 0% CPU activity in Task Manager.

Please would somebody point me in the direction of the SCCM logs we need to be checking to troubleshoot this issue further?

Many thanks
