Overview

In this article, we’ll focus on resolving the issue described as: “No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept. [ERROR_REQ_NOT_ACCEP (0x47)]”. This error, identified by the error code Error Code 71, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code 71 typically appears when attempting to establish a connection between two computers or devices over a network, usually when trying to access shared resources or remote desktops. It often indicates that the maximum allowed connections to the remote machine have been reached.

Common Fixes

1. Restart the Affected Computer

A simple restart of the affected computer can often resolve this issue. This will close all active connections and allow you to re-establish them.

2. Check Network Settings

Ensure that the network settings on both computers or devices are correct and that they are connected to the same network. Additionally, ensure that any firewalls or antivirus software are not blocking the connection attempt.

3. Increase the Maximum Connections Limit

On the remote computer, you can increase the maximum allowed connections limit by using the Windows Registry or Group Policy.
– Registry:
– Open Registry Editor (regedit) and navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
– Create or modify the MaxLanmanSess DWORD value and set it to an appropriate number.
– Group Policy:
– Open Group Policy Editor (gpedit.msc) and navigate to:
Computer Configuration\Administrative Templates\Network\Network Connections\Windows Firewall\Domain Profile
– Enable the policy Limit number of concurrent connections per session and set the number limit.

4. Use Remote Desktop Connection Manager

For remote desktop connections, you can utilize the Remote Desktop Connection Manager utility (mstsc.exe /admin) to bypass the connection limit. This will require administrator privileges.

Advanced Troubleshooting

1. Disable Unused Services

Some unused services might be occupying connections silently. Open Task Manager, sort by “Network” usage, and disable unnecessary services.

2. Check for Malware

Malware can sometimes hijack connections. Run a malware scan using a reputable antivirus or anti-malware software to identify and remove any infections.

3. Reinstall Network Adapter Drivers

Outdated or corrupted network adapter drivers can also cause this issue. Try reinstalling the drivers by right-clicking on the network adapter in Device Manager, selecting “Uninstall device,” and then restarting the computer to install the default drivers.

Conclusion

By implementing the solutions outlined in this article, you can effectively resolve the Error Code 71 issue and restore optimal network connectivity. Additionally, keeping your system up to date with the latest software and security patches can help prevent future occurrences of this error.
