DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

After upgrading to DX UIM 23.4, it is no longer possible to access the online / web Nimsoft archive through the Infrastructure Manager (IM).

When accessing the archive node, it loads and then prompts a "proxy login"

Our primary hub machine (where the IM is installed) connects to the internet via a proxy. Before the upgrade (DX UIM 20.4CU7) opening the archive was possible. 

While this issue occurs, It is still possible to connect to the archive via the Admiconsole (Configure the Admin Console to access the Web Archive using a Proxy Server)

Environment

DX UIM 23.4.*

Cause

The security Enhancement introduced in DX UIM 23.4 cause this issue.

In DX UIM 23.4 and later, the connection to the archive via the IM was upgraded from HTTP to WinHTTP (more secure). The proxy settings must allow WinHTTP through the proxy. Not having this enabled, will cause the described issue. Proxy setting only set for HTTP will not allow proxy connection established using WinHTTP.

Resolution

Steps to resolve this issue: 

  1. First verify if the proxy IP is configured to allow connections established using WinHTTP (which is what the IM will use)

    On windows, open an Administrator session of command prompt and run the following command to check the proxy settings and verify if WinHTTP is configured.

    netsh winhttp show proxy 

    If the output of the command shows as below, it means that a proxy is not configured and that you must go to step 2 and configure it. 




  2. if winHTTP is not set for your proxy server IP.  Run the following command with the proxy replacing <##.##.###.##:###>:<proxy_port> with the proxy server Ip and port. 

    netsh winhttp set proxy <##.##.###.##:###>:<proxy_port> 


    Example enabling winHTTP for IP 10.10.10.20 and port 8080

 

Note: in case winHTTP is not set, and HTTP is set already on source "ie" (internet Explorer), run the following command

netsh winhttp import proxy source=ie
