Interesting error. :-)

Which version of SQL Server do you have, including service pack (on
both sides)? Also, since the MDAC be involved, which OS versions do
you have?

Also try this syntax:

Update [Hp-server].Newexec.dbo.Customers_CoypTest
set Unitname= (SELECT b.Unitname
FROM Newexec.dbo.Customers_CoypTest b
WHERE a.Cid=b.Cid and b.Cid='Tony')
from [Hp-server].Newexec.dbo.Customers_CoypTest a join
