Cause
Windows Server 2003 Service Pack 1 and Windows Server 2003 R2 restrict permissions on COM services.
Whether Conferencing Manager is installed before or after Windows Server 2003 Service Pack 1 or Windows Server 2003 R2, you must manually set the permissions for Conferencing Manager services. Conferencing Manager does not set permissions during installation on the two services that are created, Citrix Conference Room Organizer and Citrix Conference Room.
Resolution
At the Conference Organizer server:
1. Open the Component Services administrative tool (Start > All Programs > Administrative Tools > Component Services).
2. From the console tree, expand the Component Services > Computers folders.
3. Right-click My Computer, then click Properties.
4. Click the COM Security tab.
5. From the Launch and Activation Permissions area, click Edit Limits > Add and add the following users/groups:
??é·‰G Authenticated Users
??é·‰G Network Service
6. Assign the following permissions to the groups:
??é·‰G Local Launch
??é·‰G Remote Launch
??é·‰G Local Activation
??é·‰G Remote Activation
7. Click OK twice to close the dialog boxes.
8. From the console tree of the Components Services administrative tool, expand the Component Services > Computers > My Computer > DCOM Config folders.
9. Right-click Citrix Conference Organizer, then click Properties.
10. Click the Security tab.
11. From the Launch and Activation Permissions area, click Customize > Edit > Add and add the following users/groups: Authenticated Users and Network Service.
12. Assign the following permissions to the groups:
??é·‰G Local Launch
??é·‰G Remote Launch
??é·‰G Local Activation
??é·‰G Remote Activation
13. In the Access Permissions area, click Customize > Edit > Add and add the same users/groups and permissions as you did for the Launch and Activation Permissions area.
14. Click OK twice to close the dialog boxes.
At the Conference Room Manager server, to set the Conference Room Manager service permissions, perform the previous procedure with the following exceptions:
??é·‰G In Step 5, do not add the Network Service group unless the Conference Room Manager and Conference Organizer services are on the same server.
??é·‰G In Step 9, right-click Citrix Conference Room Manager instead of Citrix Conference Organizer.
??é·‰G In Step 11, do not add the Network Service group.
