Immediately after the endpoint agent is installed, some financial endpoints may experience abnormal online banking controls, or the USB security token cannot be recognized/called, etc. Such issues are usually related to network filtering/driver compatibility on the endpoint side.

#### **Option 1: Configure Net parameters (recommended to try first)**

1\. Hold down

`Shift`

and click

**System Settings**

2\. Enter

**Net**

\->

**Parameter Settings**

3\. In parameter settings:

-   Fill in `*` in "Executable Module"
-   Fill in the relevant online banking domain name information in the "Domain" content
-   Domain name format supports wildcards, for example: `*ccb*`, `*.ccb.com`

> Example description:
> 
> -   Examples of China Construction Bank domain names: `b2b3.ccb.com`, `b2b.ccb.com`, which can be filled in in "Domain": `*ccb*`
> -   ICBC cannot access: You can fill in the "domain": `*icbc*`

4\. After filling in, click

**OK**

\->

**Apply.**

The endpoint agent computer needs to be restarted to take effect.

#### **Turn off Net related compatibility modules (use with caution)**

When the solution still cannot be solved after configuring the first solution, and priority needs to be given to ensuring the continuity of online banking business, the

**Net related compatibility module**

of the endpoint agent can be temporarily closed. This operation may affect some network-related capabilities. It is recommended to use it only when necessary, and evaluate whether it needs to be restored after verifying that online banking is restored.

**Possible scope of impact (example):**

-   Audit and control capabilities related to website access
-   Network access control capabilities

**Operating steps:**

-   In the Management Console interface **Hold `Shift`** and click **System Settings**
-   Enter **Net**
-   Select **Close/Disable Net related compatibility modules** -> click **Apply**
-   **Restart the endpoint agent computer** and it will take effect.

> Recommendation: This solution is suitable for compatible processing of specific financial endpoints, and it is not recommended to turn it off uniformly across the entire network. If long-term shutdown or batch processing is required, please contact technical support to assist in assessing the scope of the impact and alternatives.
