how to check Netweaver Version

hi Friends,

I have a doubt as how to determine the Netweaver version,

As i have installed ECC6.0 (i.e. ERP 2005) and its based on Netweaver 2004S

But still how can i find out whether its

SAP NetWeaver 7.1

                or

NetWeaver 7.0 (= NetWeaver 2004s),

Waiting for your reply...

Regards

Aayush
