I have a site built on asp and mssql express. All worked smoothly localy until the day I changed form xp to vista. I put again mssql and connect fine but when the script asks via ADO to add or update a record this error comes up:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC SQL Server Driver][SQL Server]Could not find server 'NAME\SQLEXPRESS' in sys.servers. Verify that the correct server name was specified. If necessary, execute the stored procedure sp_addlinkedserver to add the server to sys.servers.

I am not good at databases. Any help would be appriciated I am desperate
