Undocking laptop produces ODBC call failed

When I undock the computer from the port rep, I receive the following ODBC
error, even though it is a local database.

[Microsoft][ODBC SQL Server Driver][DBMSLPN] Connection Write (send()).
(10054)
[Microsoft][ODBC SQL Server Driver][DBMSLPN] General network error. Check
your network documentation. (11)
ODBC -- call failed. (3146)

I have a Vista tablet PC that runs a third party software connected to a SQL
Server Express (SP2) installed on that tablet. The software runs fine when
the unit is docked or undocked. But the process of UNDOCKING seems to
produce this error.

I tried SQL Native Client ODBC with similar results, except the message
includes "The semaphore timeout period has expired. (121)"

ODBC settings:
- System DSN
- Windows Authentication
- Default database specified
- ANSI quoted identifiers
- ANSI nulls
- Perform translation for character data

FYI, this Database is a pull subcriber to a merge replication pubication (SQL
Server 2005 SP2).

Any suggestions or advice is appreciated,
thanks.

Resolved with creating a SQL Native Client ODBC DSN and explicitly
specifying the servername (not "(local)").
