Did this fix the problem?
The TcpMaxDataRetransmissions parameter controls the number of times TCPretransmits an individual data segment (non connect segment) before endingthe connection. The retransmission timeout is doubled with each successiveretransmission on a connection. It is reset when responses resume. Thebasetimeout value is dynamically determined by the measured round-trip time onthe connection.
The Default Value for this registry entry is 5; double this value to 10(Decimal) (see step 2 above). If connection timeouts still occur, trydoubling the value again to 20 (Decimal).
Note This registry entry may only reduce the number of connection timeouterrors that occur. Changes to your Internet connection or router may haveto be made to completely resolve the problem.
