Share the knowledge

When users are unable to log into a POLLUTE 10 or MIGRATE 10 network installation, the issue is usually related to one of the following:

  • Incorrect server name or IP address
  • TCP Port 3002 blocked by a firewall
  • The License Manager service not running
  • Client computers unable to communicate with the server
  • Incorrect network license settings on the client

This guide explains how to verify the server connection, test the IP address, confirm the network port is open, and troubleshoot common network login problems for POLLUTE and MIGRATE version 10.


Understanding How POLLUTE and MIGRATE 10 Network Licensing Works

POLLUTE and MIGRATE 10 use a centralized License Manager service running on the server. Client computers connect to the server over the network using:

  • A server name or IP address
  • TCP Port 3002

The client communicates with the License Manager service to:

  • Authenticate users
  • Request concurrent licenses
  • Access network databases and projects

If the client cannot reach the server or the port is blocked, users will be unable to log in to the network license system.


Step 1 – Verify the License Manager Service is Running

Before troubleshooting the network connection, first confirm the POLLUTE/MIGRATE License Manager service is running on the server.

How to Check the Service

On the server computer:

  1. Open:
    • Control Panel
    • Administrative Tools
    • Services
  2. Locate:
    • PMLicenseManager
  3. Verify the service status is:
    • Running

If the service is stopped:

  1. Right-click the service
  2. Select:
    • Start

The service should normally be configured to start automatically with Windows.


Step 2 – Verify the Correct Server Name or IP Address

Client computers must point to the correct network server.

Where to Configure the Network Address

On the client computer:

  1. Open POLLUTE or MIGRATE
  2. Select:
    • File > Preferences
  3. Open:
    • Network License
  4. Verify:
    • Networked = Yes
    • Correct server name or IP address
    • Port = 3002

If the server name is incorrect or misspelled, the client will not be able to connect.


Step 3 – Find the Correct Server IP Address

If users cannot connect using the server name, try using the server IP address instead.

How to Find the Server IP Address

On the server:

  1. Open Command Prompt
  2. Type:
ipconfig
  1. Press Enter

Look for:

IPv4 Address

Example:

IPv4 Address . . . . . . . . . . : 192.168.1.25

This is the IP address clients should use in the POLLUTE/MIGRATE Network License settings.


Step 4 – Test Network Connectivity Using Ping

After obtaining the server IP address, test whether the client can reach the server.

Test the Server Connection

On the client computer:

  1. Open Command Prompt
  2. Type:
ping 192.168.1.25

(Replace the IP address with your actual server IP.)

If successful, you should receive replies such as:

Reply from 192.168.1.25: bytes=32 time<1ms TTL=128

What If Ping Fails?

If you receive:

Request timed out

or

Destination host unreachable

then:

  • The server may be offline
  • The client may be on the wrong network
  • Windows Firewall may be blocking traffic
  • VPN settings may be preventing communication
  • The server name may not resolve correctly

Before proceeding, confirm:

  • Both computers are on the same network
  • VPN connections are functioning properly
  • Firewalls allow internal communication

Step 5 – Verify Port 3002 is Open

Even if the client can ping the server, the required license port may still be blocked.

POLLUTE and MIGRATE 10 network licensing normally communicate using TCP Port 3002.


Method 1 – Test the Port Using Telnet

Enable Telnet (If Needed)

On Windows:

  1. Open:
    • Control Panel
    • Programs and Features
    • Turn Windows Features On or Off
  2. Enable:
    • Telnet Client

Test the Port

On the client computer:

telnet 192.168.1.25 3002

If the connection succeeds:

  • The screen will go blank
  • This indicates the port is open

If you receive an error such as:

Could not open connection

then Port 3002 is blocked or the License Manager service is not listening.


Method 2 – Test the Port Using PowerShell

Modern versions of Windows can test ports using PowerShell.

On the client:

Test-NetConnection 192.168.1.25 -Port 3002

If successful, you should see:

TcpTestSucceeded : True

If it says:

TcpTestSucceeded : False

then the client cannot reach the License Manager service on Port 3002.


Step 6 – Open Port 3002 in Windows Firewall

If the port test fails, Windows Firewall may be blocking the connection.

Open Port 3002 on the Server

On the server:

  1. Open:
    • Windows Defender Firewall
    • Advanced Settings
  2. Select:
    • Inbound Rules
  3. Click:
    • New Rule
  4. Choose:
    • Port
  5. Select:
    • TCP
  6. Enter:
    • 3002
  7. Select:
    • Allow the connection
  8. Apply the rule to:
    • Domain
    • Private
  9. Name the rule:
    • POLLUTE/MIGRATE License Manager

Repeat the same process for Outbound Rules if required by your IT security policies.


Step 7 – Verify the License Server is Listening on Port 3002

On the server computer:

  1. Open Command Prompt
  2. Run:
netstat -an | find "3002"

You should see something similar to:

TCP    0.0.0.0:3002     LISTENING

If nothing appears:

  • The License Manager service may not be running
  • Another application may already be using Port 3002
  • Firewall or antivirus software may be interfering

Step 8 – Verify Client License Settings

Sometimes the connection succeeds but the client is configured incorrectly.

On the client computer verify:

  • Networked = Yes
  • Correct server name or IP address
  • Port = 3002
  • Required modules selected

After changing settings:

  1. Click OK
  2. Restart the application

Step 9 – Check Active Locks and Logs

The License Monitor includes tools to help diagnose login problems.

Active Locks

The Active Locks window displays:

  • Current users
  • Active licenses
  • Computer locations
  • Module usage

If all licenses are already in use, additional users may be denied access.


Review the Event Log

The Event Viewer records:

  • Login attempts
  • License requests
  • Connection failures
  • Authentication issues
  • Network errors

Reviewing the logs can often identify the exact reason users cannot connect.


Common Causes of Network Login Problems

ProblemPossible Cause
Cannot ping serverNetwork connectivity issue
Ping works but login failsPort 3002 blocked
Port test failsFirewall or service issue
Login window appears repeatedlyIncorrect IP or hostname
User denied accessNo available concurrent licenses
Users disconnect randomlyVPN or unstable network
Server name fails but IP worksDNS resolution problem

Best Practices for Reliable Network Licensing

To minimize network login problems:

  • Use a static IP address for the server
  • Keep Port 3002 open internally
  • Avoid changing the server hostname
  • Exclude the License Manager from antivirus scanning
  • Monitor license usage regularly
  • Ensure the License Manager service starts automatically

Final Thoughts

Most POLLUTE and MIGRATE 10 network login problems can be resolved by verifying:

  1. The License Manager service is running
  2. The server IP address is correct
  3. Port 3002 is open
  4. The client can reach the server
  5. The network license settings are configured properly

Using tools such as ping, telnet, Test-NetConnection, and netstat can quickly identify where communication is failing and help restore user access to the network license server.
