Cannot browse particular ObjectFolder

Hi All,

I have been using the recursive browse example provided here (C#):

www.opclabs.com/files/onlinedocs/OPCLabs-OpcStudio/Latest/Us...wse%20nodes%20recursively.html

Although we have one ObjectFolder that the client seems to skip or cannot access. Both Kepware and Matrikon can see the child objects although for some reason I cannot retrieve this via the OPC-UA client using a command line app. Other ObjectFolders seem to work fine and all child items populate within the console.

The NodeId of the object is ns=3;s=0:#c1 which sits under another object s=BrowseProvider in the root namespace. I have tried explicitly specifying the NodeId as part of UANodeDescriptor but cannot seem to get any child nodes under that particular NodeId. As far as I know, the characters within the identifier are compliant so I am not sure what the issue is with this particular Object; especially since both Kepware & Matrikon can browse this tree.

Is there something I am missing? We have two servers with the same ObjectFolder structure, and I cannot seem to recursively obtain the child nodes out of either of the servers.
