This is the error message I received while using Administrative Tools > Disk Management in order to assign the drive letters for an external hard drive. It is now about two months after installing SP3 for Windows XP Professional, so, perhaps, this might be one result of SP3's many bugs, err features that were reported by thousands of XP users after installing SP3.
Web searching so far has found that many have had this particular problem over the past several years. Therefore, SP3's installation seems to not be the culprit due to this happening over seven years ago for some early XP users. One error message said to make sure that dmremote.exe was added to the Exceptions list in Windows Firewall. However, adding it to the Exceptions did not restore the functioning of Disk Management.
Moving right along... The next error message suggested that RPC port be added to the Exceptions list using TCP port 135. Adding TCP port 135 also to the firewall exceptions did not enable Disk Management to return. In fact, disabling Windows Firewall also did not allow Disk Management to function as it always had worked fine earlier, so it appears likely that adding anything to the Exceptions list will not, in itself, rectify this problem.
Another error message upon starting the LDM was:
"Logical Disk Manager (LDM) is not registered. LDM supports Windows 2000 or later. Check the operating system version on the computer named ...". This error message seems to indicate that the Windows Registry is the source of the LDM's misfunctioing.
Open the Computer Management dialog box by right-clicking My Computer on the Desktop and choosing Manage.
Then double-click on Services and Applications on the left and then click on Services.
and enable the following services and set the values in the Windows (here, it is XP Pro SP3) Registry according to the custom values or other information on this website (BlackViper.com):
- Logical Disk Manager
- Plug and Play
- Remote Procedure Call (RPC)
- Logical Disk Manager Administrative Services[/url
- COM+ Event System
- COM+ system application
- Volume Shadow Copy
- System Event Notification
