Question

i am using IIS6

Answer 1

It's best practice to make this a new account that you can control the direct privileges too, since Network Service can have a bit higher level of permissions. You can change this under the Application Pool in IIS that your website hosting WCF is running as.

Then wherever your website needs the read/write access grant to this new account.
