IIRC, for mount.nfs, the "r" option is read only while the "w" option is read+write. They may be mutually exclusive.
I don't believe this is accurate. ro and rw are mutually exclusive, but there is no "w" option. (Which doesn't help the OP, unfortunately, but at least he knows.)
For the OP, you should check the system logs on both the client and the server. There may be clues as to what the real error is; sometimes mount.nfs reports a misleading error when the actual problem is somewhere else.
