Summary
The OfficeScan NT Proxy Service hooks the User Datagram Protocol (UDP) network connection and prevents third-party VPN software from working.
Details
To prevent OfficeScan clients from hooking the UDP network connection, do one of the following procedures depending on your version:
For OfficeScan 10.5
- Install at least Patch3 for OfficeScan 10.5.
- Open the ofcscan.ini file in the ..\PCCSRV folder in the OfficeScan installation directory.
- Add the "TmtdiAttachUDP" key under the Global Setting section of the ofcscan.ini file and set its value to "0".
[Global Setting]
TmtdiAttachUDP=0 - Open the OfficeScan server web console and go to Networked Computers > Global Client Settings screen.
- Click Save to deploy the setting to all clients.
The OfficeScan client program automatically installs the following registry key:Path: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\tmtdi\Parameters]
Key: AttachUDP
Type: dword
Value: 0
For OfficeScan 10.6
Note: This function must be enabled on every client machine.
- Unload the OSCE client.
- Add the registry key "AttachUDP".
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tmtdi\Parameters]
AttachUDP=0 (DWORD) - Reboot the machine.
