Crystal Report: Logon failed

[Ben]

Hi

We have been developing an intranet using VB .NET displaying crystal
reports.

We repeatedly receive the error below on both the development machine and
the deployment server:

I have read the information on many sites and followed instructions with no
luck, any help would be much appreciated.

Thanks
B
