Hai, 

On the windows pc, run : 
	CMD  
	ipconfig /all 

Verify if DNS suffix and Connection DNS suffix are correctly set. 
Also, by default the reverse records are not updated/added. 

In GPO you can add : 
Group Policy:
Computer Configuration
    Network/DNS Client
        Policy
        Dynamic Update = Enable
        Register PTR Records = Enabled
            Register PTR Records: Register only if A record registration succeeds

No GPO, look here,

Greetz,
