Hello,
I am sorry but I do not have a direct answer - I have to start by asking for more details.

Are you getting Access Denied only with browsing? Or, are there other methods that work well? If so, which methods please?
Is the Access Denied consistent - that is, is no browsing possible at all, or is it only from time to time?
Have you tried browsing for items using some other OPC client on the same machine where your application with QuickOPC is running? If so, do they work well?
There have been some security-related changes to our software, around March 2012. Are you using the latest build (available from the Downloads page - currently 5.12.1305.1)?

Thank you, and best regards
