Dial up connection is connected, but Windows Vista says it is not.

I got a virus and did a factory image reset, installed sp1 and sp2, then I started dowloading the updates. it was working fine untill the last restart.

Now the network notifaction only shows local, not my dial-up. neither does the network sharing center, under the manage network connections it does show my connection, but the IPv4 under status shows "not connected".

I did the followimg witout any fix, I tried to dail up in safe mode but could not get my modem to work.
