I have lately changed the server where my application was running from
a windows NT4/MSSQL7.0 to Windows 2000/MSSQL2000,

My application is made with Visual C++.

Before the application was running fine, and it was accessing the
database without problems, now when I have migrated the application
sometimes fails when trying to log into the database.

I get the following error:
DB-LIBRARY error:
NULL DBPROCESS pointer encoutred.

The strange part of this case is that the problem occurs maybe 50% of
times the application connects to the database.

In an other hand I have a php application that is running on the same
server, same database, and didn't suffer from any problem.

Any help would be appretiated.
