VB Error # -2147467259

Last Modified: 2013-12-25
I'm connecting to SQL Server using Excel.

Sometimes I get the message

VB Error # -2147467259
Generated by Microsoft OLE DB Provider
Cannot open database '.....' required by the login. Login failed

I get this message even though I don't change credentitals, Excel just decides to not work.

When I get this message, when opening up SQL Serve Management studio, the database is visible but doesn't have a '+' next to it, so can't see tables etc.

A reboot fixes things....

Help please for why this is occuring and how I can avoid having to always reboot, thanks
Watch Question


Its Excel 2002 I'm running
The conncetion string is like this:

 "Provider=SQLOLEDB;Data Source=.\SQLEXPRESS;Initial Catalog=xxxxx;Integrated Security=SSPI;"
so you are using Windows Authenticated user to connect. Please check the login user has rights to connect to ther sql server.


using Windows Authenticated user to connect: that is correct

login user has rights to connect to ther sql server:  the same user can sometimes log-in; another time they can't, just minutes afterward
What is your maximum concurrent user connection set to?
Look In Enterprise Manager, right click the server properties->connection tab. Let me know, if is it set to 0 (unlimited) or something else?


it is set to zero


any more ideas?

AFTER I can no longer connect from VBA in  Management studio when I try to connect to database I get message

Error Database cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server error log for details
the files aren't read only

I can see the database but no '+' next to it like the others (or like it after a reboot/during when macros are going fine)
