We loaded an OPC server package on a Windows 2000 Pro machine and the Network icons in network and dialup connections disappeared. The local are network connection is still working but we can't make any changes to it. I think some thing got changed in the registry. Also we are unable to add any new connections using the one icon make new connection that is left. Does anyone have an idea how to fix this?

I would recommended to do the following step:

1. Start Notepad.
2. Type the following lines in Notepad:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Interface\{0000010c- 0000-0000-C000-000000000046}]@="IPersist"

[HKEY_CLASSES_ROOT\Interface\{0000010c- 0000-0000-C000-000000000046}\NumMethods]
@="4"

[HKEY_CLASSES_ROOT\Interface\{0000010c- 0000-0000-C000-00000000004
ProxyStubClsid32]@="{00000320-0000-0000-
C000-000000000046}"

3. Save the file as Restore.reg. Note that
Notepad may add a .txt extension to the file
name. If this occurs, rename the file to
Restore.reg.

4. Double-click theRestore.reg file.
5. When you are prompted to confirm that you
want to add the information to the registry,
click Yes.
6. Restart your computer.

I checked the registry and values are set as in answer. What I did see is that on the machine that does NOT work right the following folder is missing: OLEViewerIViewerCLSID with ab default of "{7CE551EB-F85C-11CE-9059-080036F12502}"

What does HKEY_CLASSES_ROOT\Interface\{0000010c- 0000-0000-C000-000000000046} do?

I have 3 Dell 4600's and 1 1650 and it has happened to all of them. The only thing that they had in common is that they were Dell and I had installed the OS using Dell's server assistant CD as well as SP3. One of those servers was running OPC serveras well but the other ones were not. I do not think that it is the OPC server. My suspicions are that the Server Assistant CD is the culprit or SP3. I have since re-installed Win2k server without the server assistant CD and went back to SP2. All is working well now.

The problem turned out to be in DCOM configuration. When we had default Authentication level set to none and default Impersonation level set to Anonymous the network icons disappeared. When we change Anonymous to Impersonate and rebooted the Iconsreturned.
