In your Control Panel, what does it say precisely about the OPC Core Components? In the Add/Remove Programs, what is in the "Name" column, and what is in the "Version" column?
Thank you

I can browse servers in the local computer.
After I wrote this line:
EasyDAClient.SharedParameters.Machine.BrowseFromRegistry = false;
Exception no longer occurs, returns an empty list of servers for the local computer and the remote.
I also installed QuickOpc on both computers, so OPC Core components are everywhere.

this is an unusual error. I do not know the cause, but can you please provide some more bits of information?
- Which version and build of QuickOPC are you using?
- Is the client computer 32 or 64 bit system? And the server (remote) computer?
- Does the BrowseServers work locally, or on other remote computers?
- Please try disabling remote registry browsing:
EasyDAClient.SharedParameters.Machine.BrowseFromRegistry = false;
Also
- Can you please check that recent OPC Core Components are installed on both sides, from www.opcfoundation.org .
- Note that the parameter you are setting (ClientParameters.UseCustomSecurity) only affects connections to OPC servers that are already identified. If you intent was to influence the parameters for the BrowseServers, the corresponding (same named) parameters are in the MachineParameters.

I'm trying connect to the remote server and I get the error OPC operation failure.
I tried to connect with another client, the server list is returned.
DCOM is configured.
I'm used this code:
EasyDAClient.ClientParameters.UseCustomSecurity = false;
EasyDAClient cl = new EasyDAClient();
var f = cl.BrowseServers("dms8000");
