Error V-138-5224-1020 while adding user to DLO Console

Hi

I am getting the below error while trying to add a user manually to the DLO Console.

   Error V-138-5224-1020

   Unable to add user domain\username. The system returned the

   following message: 80040e2f

Automated user assignment is also not working, so I was adding users manually. I recently deleted many users, these

are the only changes I've made since it stopped working for all users.

I have also tried updating the XPDLOShareu.dll file as indicated in the below link:

http://www.symantec.com/business/support/index?page=content&id=TECH59003

From this link I am also unable to run the commands to update the DLO database. On my DLO server the XPDLOShareu.dll

is located in the  C:\Program Files (x86)\Microsoft SQL Server\MSSQL.1\MSSQL\Binn

folder as opposed to C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn

I'm using DLO version 7.5

Any assistance in helping resolve this issue is greatly appreciated

Thanks

Jimmy
