Troubleshooting DPM
• If you are getting "Access Denied" errors when DPM is performing a task that
involves communication with a protected computer such as synchronizing;
this issue could be caused by one of two things:
° The system time on the DPM server and the protected computer are
not synced with the same time server. (The domain controller in a
network is typically the time server.)
° It could be the DPM server does not have access to the Distributed
COM Users group on the protected computer. This group also needs
to have Distributed COM (DCOM) Launch and Access permissions
on the protected computer.
To verify the DPM server's membership to the Distributed COM Users group on the
protected computer follow these steps:
1.
Go to the Start menu, click on Administrative Tools | Computer
Management | System Tools | Local Users and Groups | Groups .
2.
In the Details pane, double-click the Distributed COM Users group .
3.
Verify that the computer account for the DPM server is a member of
this group.
To verify the group has DCOM Launch and Access permission on the protected
computer follow these steps:
1. In Administrative Tools , open Component Services .
2. Expand Component Services | Computers , right-click My Computer , and
then click Properties .
3.
On the COM Security tab, under Access Permissions , click Edit Limits .
4.
Verify that the Distributed COM Users group is allowed both Local Access
and Remote Access permissions.
5.
On the COM Security tab , under Launch and Activation Permissions , click
Edit Limits .
6.
Verify that the Distributed COM Users groups is allowed the
following permissions:
° Local Launch
° Remote Launch
° Local Activation
° Remote Activation
