BizTalk 2020 RosettaNet Accelerator Error 2

Every time I try to configure the BizTalk Accelerator for RosettaNet in BizTalk Server 2020 using Windows Server 2019 I encounter this error in the configuration log file

[2020-03-04 16:37:40:0043 Error ConfigHelper] Failed to add member 'user' to NT Group IIS_WPG Error code: -2147022676
[2020-03-04 16:37:40:0043 Error ConfigHelper] The group name could not be found

Cause

Well, basically this is a bug that has not been fixed yet. BizTalk Accelerator for RosettaNet was introduced in BizTalk Server 2004 and since they're only a little or no changes were made.

BTARN requires the IIS_WPG group (group provided by IIS 6.0 that provides the minimum set of user rights and permissions required to run an application) but unfortunately for us, this group doesn't exist anymore...

Solution

The solution is very simple... you just need to create it manually.

To accomplish that you need to:

• Open Computer Management and in the console tree, expand "System Tools à Local Users and Groups" and then right-click Groups
• and select the option New Group
• In Group name
  • Type: IIS_WPG.
• In Description
  • Type: RosettaNet IIS group
• And then click Create, and then click Close

I really hope that Microsoft provide a hotfix for this or at least fix this problem in the next releases of the product.
