 ## Overview
 
-This error occurs when the Netwrix Auditor collector fails to establish or maintain a connection with the RPC server. Multiple factors can contribute to this issue, including network instability, antivirus interference, or insufficient system resources. The following sections provide troubleshooting steps to identify and resolve the root cause.
+This error occurs when the Netwrix Auditor File Server collector cannot establish or maintain a connection with the RPC server. Common causes include network instability, antivirus interference, or insufficient system resources. The following sections provide steps to identify and resolve these issues.
 
 ## Instructions
 
 ### 1. Connection Dropping with Compression Service During Data Collection
 
-When collecting data from the Target Audited Server, it's vital to maintain a stable and reliable connection with the Compression service. However, sometimes issues may arise when this connection drops. This can often be attributed to network instability, which disrupts proper data transmission. In such cases, the focus should be on addressing the underlying causes of network instability. This may involve inspecting and configuring network equipment to ensure a consistent and robust connection, thereby allowing the data collection process to complete without interruptions.
+When collecting data from the target audited server, it is essential to maintain a stable and reliable connection with the **Compression service**. Network instability can interrupt data transmission and cause connection drops.
+
+To resolve this issue:
+
+- Inspect and configure network equipment to ensure a consistent connection.
+- Verify bandwidth stability and latency thresholds.
+- Test network reliability between the **Auditor Server** and **target audited server**.
+
+Maintaining a stable network connection helps the data collection process complete without interruption.
 
 ### 2. Unstable Connection During Large-Scale Audits
 
-When conducting large-scale audits, maintaining a stable connection is critically important. An unstable connection can lead to interruptions, making it challenging or even impossible to carry out the audit in its entirety. An effective strategy for resolving this issue is to break down the initially large audit scope into smaller, more manageable parts. For instance, instead of using the entire Target Audited Server with all shares as an item, it is better to add shares of the Target Audited Server individually as separate items. This approach reduces network load and minimizes the risks associated with connection loss. Segmenting the audit allows for phased execution, contributing to more successful completion of each phase and, ultimately, the entire audit.
+During large-scale audits, unstable connections may interrupt or halt the audit process. To reduce connection load and improve performance:
+
+- Divide large audit scopes into smaller, manageable items.
+  - For example, instead of adding the entire target audited server with all shares as a single item, add each share separately.
+- Segment the audit into phases to reduce network load and improve reliability.
 
-> **NOTE:** This recommendation pertains to critically important audit objects, not to the entire audited scope. For example, if the entire file server is added to the audit collection, but auditing multiple shared folders on this server isn't necessary, it's recommended to exclude these folders from collection using "excludes." This way, the collector will gather only what is required for auditing, dedicating all its resources to this task.
+> **NOTE:** Apply this recommendation to critical audit objects only. For example, if a file server includes many shared folders but not all need auditing, exclude the unnecessary folders using **Excludes**. The collector will then focus on necessary data only.

-### 3. Antivirus Interference on Netwrix Auditor Server and/or Target Audited Server with Netwrix Auditor and Compression Service
+### 3. Antivirus Interference on the Auditor Server or Target Audited Server
 
-Antivirus programs on both the Netwrix Auditor Server and the Target Audited Server are vital for protecting data and systems from malicious threats. However, they can sometimes interfere with the proper functioning of Netwrix Auditor. This can occur for several reasons:
+Antivirus software is essential for system protection but can sometimes interfere with Netwrix Auditor or its **Compression service** by blocking or delaying connections.
 
-* **Connection Blocking:** Antivirus programs may interpret some legitimate network connections as potential threats, resulting in their blockage. This can disrupt the interaction between Netwrix Auditor and/or Compression service.
-* **Traffic Scanning:** The process of scanning incoming and outgoing traffic can slow down data transmission, affecting Netwrix Auditor's performance. The antivirus may delay data packets, suspecting potential threats.
-* **False Positives:** Occasionally, antivirus programs may mistakenly identify harmless files or processes as malicious, leading to their isolation or deletion, which can disrupt the operation of Netwrix Auditor and/or Compression service.
+Common interference causes include:
 
-To mitigate these issues, it is crucial to add Netwrix Auditor processes and services to the antivirus exclusion list according to the following guidelines:
+- **Connection blocking:** Legitimate network connections may be flagged as threats and blocked.
+- **Traffic scanning:** Continuous scanning may delay or disrupt communication.
+- **False positives:** Antivirus may isolate or delete Auditor or Compression service files.
 
-### Netwrix Auditor Server:
+To prevent this interference, add the following exclusions to your antivirus configuration.
+
+#### Netwrix Auditor Server
 
 **Paths:**
+
 - `C:\ProgramData\Netwrix Auditor`
 
-  **Note:** If you've previously changed the default location, you can look up the default value in the registry key:
-  `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Netwrix Auditor\DataPathOverride`
+> **NOTE:** If the default data location has changed, verify the current path in the registry key:
+> `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Netwrix Auditor\DataPathOverride`
 
 **Processes:**
+
 - `NwFileStorageSvc (NwCoreSvc.exe)`
 
-### Target Audited Server (if Compression service is enabled):
+#### Target Audited Server (if Compression Service Is Enabled)
 
 **Paths:**
+
 - `C:\Windows\SysWOW64\NwxExeSvc`
 
 **Processes:**
+
 - `NwxExeSvc.exe`
 - `NwxFsAgent.exe`
 - `NwxEventCollectorAgent.exe`
 - `NwxSaclTunerAgent.exe`
 
-For a comprehensive list of antivirus exclusions and additional guidance, refer to [Antivirus Exclusions for Netwrix Auditor](/docs/kb/auditor/antivirus-exclusions-for-netwrix-auditor).

+
+### 4. Insufficient Disk Space on the Target Audited Server
+
+Low disk space on the agent’s system drive can cause the **Compression service** to malfunction or fail.
+
+To resolve:
+
+- Free up disk space by removing unnecessary files or logs.
+- Move large data files to secondary storage.
+- Extend the disk volume if necessary.
+
+Ensure that sufficient free space exists for both system operations and Netwrix Auditor processes.
 
-### 4. Insufficient Disk Space on the Target Audited Server's System Disk
+### 5. Insufficient System Resources (CPU or RAM) for the Compression Service
 
-When the agent's system disk runs low on free space, it can lead to reduced system performance, inability to install updates, and errors in Compression service operation. Resolving these issues involves freeing up disk space by removing unnecessary files and data, transferring information to other storage devices, or increasing the disk space capacity.
+If the target audited server lacks sufficient CPU or RAM resources to handle large audit volumes, the **Compression service** may fail or slow down significantly.
 
-### 5. Insufficient Resources (CPU, RAM) for Compression Service Due to Large Audit Volume
+Recommended actions:
 
-When the Target Audited Server does not have enough free CPU and RAM resources to handle a large audit volume, the Compression service may become overwhelmed, unable to handle the load. This, in turn, can lead to network overload and increase the likelihood of errors during data transmission. To improve the situation, consider segmenting the audit scope, excluding unnecessary scope from the audit, or adding more CPU and RAM resources to the Target Audited Server.
+- Segment or limit the audit scope to reduce processing demand.
+- Exclude unnecessary targets from the audit.
+- Increase available CPU and memory resources on the target server.
