Resolving “Server Error in Application “LicenseUI” when accessing the Dell Connections License Manager Web UI

This post was written by Raghavendran N of the Dell OpenManage Integrations team.

Symptom: HTTP error 500.19 shows up (captured in the screenshot below) while accessing the Dell Connections License Manager Web UI (http://<ipaddress>:8544/DellLicenseManagement).

Reason: WSUS (Windows Server Update Services - http://en.wikipedia.org/wiki/Windows_Server_Update_Services) is installed on the server that is running the Dell Connections License Manager.

Steps to resolve the error:

Please use the options below depending on your system configuration:

  1. Disable the XPress decompression scheme using the command:

%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']

  1. Add an attribute of "precondition= "64bitness" for the “DynamicCompressionModule” entry so that it loads only in 64bit application pools.
  2. Use 32 bit version of suscomp.dll.
