Slow Excel exportation

Hello group, I’ve an issue with one user only, when he wants to export to Excel one developed report, it took more than hour exporting about 5000 records. I’ve already delete the zup file and nothing changes, the environment is as the following;

Dynamics Nav 5
The user opens Nav through remote desktop in the server
SQL Server Database
The Nav user is an LDAP account
Using Excel buffer

The same user logged in another workstation has the same problem, and other user in the workstations the user with the problem can export this report in 3 minutes.

Thanks in advance. Best Regards

Solved!!! the user doesnt have dimension filters in the table 91.
