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.
