Hi Talis,

The second NetShareEnum is probably just a fail-over reaction to the
DCERPC call failing. The only way to see why you're getting an
"Unexpected DCERPC PDU header" error would be to get a network packet
capture. If you can get a capture and send it to me directly (do not
post captures to the mailing list), I might be able to tell you more.

Mike
