unexpected protocol charactor during authentication

"Test connection failed because of an error in initializing providor.
Unexpected protocol charactor during authentication; Socket has been
closed."
The above is the error I get from ODBC in Visual Basic when hiting "Test
Connection" when connecting via SSH tunnel to the server.

PgAdmin spit out the following Debug info also:
-- Debug output --

This happened after we took down the PostgreSQL database after upgrading to
7.2 to the old 7.1 version long enough to dump a database which we restored
to the 7.2 version... when we brought it back up... all of our applications
no longer worked, nor did PgAdmin II. Although PHP and the PgSQL tools work
fine.

Any ideas?

Thanks,
