Every time I try to configure the BizTalk Accelerator for RosettaNet in BizTalk Server 2013 or BizTalk Server 2013 R2, of course, using Windows Server 2012 or Windows Server 2012 R2, I encounter this error in the configuration log file
[2015-05-14 16:37:40:0043 Error ConfigHelper] Failed to add member ‘user’ to NT Group IIS_WPG Error code: -2147022676
[2015-05-14 16:37:40:0043 Error ConfigHelper] The group name could not be found

📝 One-Minute Brief
When configuring BizTalk Accelerator for RosettaNet (BTARN) on Windows Server 2012/R2, you may encounter Error -2147022676: “Failed to add member to NT Group IIS_WPG.” This happens because the IIS_WPG group (from IIS 6.0) no longer exists in newer Windows versions. To fix this, simply create the “IIS_WPG” group manually in Local Users and Groups before running the configuration.
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 then, only a few changes have been 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 > Local Users and Groups, and then right-click Groups.
- and select the option New Group.
- In the Group name
- Type: IIS_WPG.
- In Description
- Type: RosettaNet IIS group.
- And then click Create, and then click Close.
I really hope that Microsoft provides a hotfix for this or at least fixes this problem in the next releases of the product
