have tried hard coding the path:
\\10.0.40.33\mstest1.com\public\mstest1\data\thscD ata.accdb
in the connection string:
Data Source=\\10.0.40.33\mstest1.com\public\mstest1\data\thscData.accdb
or if you think \\10.0.40.33\mstest1.com\public\data\thscData.accdb is the coorect path try using that:
Data Source=\\10.0.40.33\mstest1.com\public\data\thscData.accdb
the server may not have the Microsoft.ACE.OLEDB.12.0 available, like i said before, so you may need to change the provider to use the Microsoft.Jet.OLEDB.4.0 provider instead.
