Moderate: Requires basic macro, coding, and interoperability skills.

This article applies only to a Microsoft Access project (.adp).



SYMPTOMS
As part of installing the Access Workflow Designer server components to a Microsoft Windows NT 4.0 computer, you do the required install of the Microsoft Windows NT 4.0 Option Pack. Later, after deploying the Issue Tracking solution, you receive the following error message when you attempt to synchronize the user list:

Userlist.Connect unable to create an instance

Access denied



CAUSE
After installing the Microsoft Windows NT 4.0 Option Pack, you changed domains for the server and then installed the Access Workflow Designer server components. The Microsoft Windows NT Option Pack hard codes the IIS Identity settings for the IUSR_MACHINENAME and IWAM_MACHINENAME accounts. So, even after your computer is moved to a different domain, these accounts still point to the "old" domain.



RESOLUTION
To resolve this problem, do either of the following:


 * Move the computer to the "new" domain and then run the Microsoft Windows NT Option Pack.

-or-


 * Manually update the DCOM permissions.

To manually update the DCOM permissions, do the following:

 Start the Distributed DCOM Configuration Properties program. On the Start menu, click Run and type the following:

dcomcnfg

Click OK. If you are prompted twice to record the Msohelp.exe file, click Yes both times. In the Applications list, scroll down and click the UserList.Connect entry. Click the Properties button. Click the Security tab. Select the Use custom access permissions item. Click the Edit button.</li> Double-click the user account that either deployed the template or previously installed the Microsoft Windows NT 4.0 Option Pack.</li> Click OK twice.</li> Shut down and restart the server computer.</li></ol>
